Mechanical Engineering Series – serie

This unique textbook features fundamentals and analyses of metal forming processes supported by 200 worked numerical examples. It provides rigorous detail on the three all-important groups of metal-forming processes: bulk-metal forming, sheet-metal forming, and sheet-bulk-metal forming.

The aim of the book is to give an up-to-date review of rotor dynamics, dealing with basic topics as well as a number of specialized topics usually available only in journal articles. Part I deals with the classical topics of rotor dynamics, the dynamic behavior of linear, steady state rotating machines; simple models as well systems with many degrees of freedom obtained from finite element models.  Part II, advanced rotor dynamics deals with some specialized topics on rotors, bearings, discs and blades.

Modeling and simulation are central to a mechanical engineer's activity. Increasingly complex models are being used routinely on a daily basis. This revolution is the result of the extraordinary progress in computer technology in terms of both hardware and software.This work deals with the control of the hypotheses leading from a mechanical model, usually coming from continuum mechanics, to a numerical model, i.e. the mastery of the mechanical computation process itself. Particular attention is given to structural analysis which, in this context, is the most advanced domain.A significant part of this work is dedicated to the application of error estimators to the control of the various parameters involved in a calculation, beginning with the parameters related to the mesh.

Mechanical engineering, an engineering discipline forged and shaped by the needs of the industrial revolution, is once again asked to do its substantial share in the call for industrial renewal. The general call is urgent as we face profound issues of productivity and competitiveness that require engineering solutions. The Mechanical Engineering Series features graduate texts and research mono­ graphs intended to address the need for information in contemporary areas of mechanical engineering. The series is conceived as a comprehensive one that covers a broad range of concentrations important to mechanical engineering graduate education and re­ search. We are fortunate to have a distinguished roster of consulting editors on the advisory board, each an expert in one of the areas of concentration. The names of the consulting editors are listed on the facing page of this volume. The areas of concentration are applied mechanics, biomechanics, computational me­ chanics, dynamic systems and control, energetics, mechanics of materials, proc­ essing, production systems, thermal science, and tribology.

Structural design sensitivity analysis concerns the relationship between design variables available to the design engineer and structural responses determined by the laws of mechanics. The dependence of response measures such as displacement, stress, strain, natural frequency, buckling load, acoustic response, frequency response, noise-vibration-harshness (NVH), thermo-elastic response, and fatigue life on the material property, sizing, component shape, and configuration design variables is defined through the governing equations of structural mechanics. In this 2-volume set, first- and second- order design sensitivity analyses are presented for static and dynamics responses of both linear and nonlinear elastic structural systems, including elasto-plastic and frictional contact problems.Book I introduces structural design concepts that include the CAD-based design model, design parameterization, performance measures, costs, and constraints. It also discusses design sensitivity analysis of linear structural systems, and discrete and continuum design sensitivity analysis methods.

Structural Synthesis in Precision Elasticity reflects the summary of theoretical and experimental studies whose conclusions are effective for optimized structural synthesis in precision elasticity, as well as demonstrate a large experience and options in the synthesis, production, application of precision elastic guides, mechanisms, correctors, transducers, instruments and machines. The main focus of this book is in the possible simplification of the corresponding analytical apparatus by using kinematical equivalents, matrix methods, appropriate contours, and function expansion with enough accurate minimal polynomials. This approach allows for substitution of some known unwieldy formulae and methods that are not convenient for digestible and tractable synthesis.The book consists of two main parts:- The elastic systems functional analysis and structural synthesis methods, including effective approximations and references to the history of their development- The application and development of precision functional elastic systems at reference and operating conditions, including the observation of archives with effective synthesized structures and elements of nanotechnology.Each part provides theoretical basics and a large variety of examples and recommendations. This book gives theoretical and practical tools to researchers, precision machines, instruments and miniature systems designers, engineers, metrologists, and engineering students.Despite that this book is dedicated to the general problems of the structural synthesis in precision elasticity, most of the practical examples and applications are concerned with the measuring systems as the precision is their main goal.The author intends to show close connection between the elastic precision structures developed during the 20th century and even before and the new elastic systems for atomic force microscopy and other recently created advanced structures in precision elasticity.

Manufacturing Systems: Theory and Practice, Second Edition, provides an overview of manufacturing systems from the ground up. It is intended for students at the undergraduate or graduate level who are interested in manufacturing, industry practicing engineers who want an overview of the issues and tools used to address problems in manufacturing systems, and managers with a technical background who want to become more familiar with manufacturing issues. The book has six chapters that have been arranged according to the sequence used when creating and operating a manufacturing system. Thus, the subjects emphasised are: the decision framework for manufacturing, the manufacturing processes, the manufacturing equipment and machine tools, the design for manufacturing and the operation of manufacturing systems. The book attempts a compromise between theory and practice in all addressed manufacturing systems issues, covering a long spectrum of issues from traditional manufacturing processes to innovative technologies such as Virtual Reality, Nanotechnology and Rapid Prototyping.

As the name implies, Intermediate Dynamics: A Linear Algebraic Approach views "intermediate dynamics"--Newtonian 3-D rigid body dynamics and analytical mechanics--from the perspective of the mathematical field. This is particularly useful in the former: the inertia matrix can be determined through simple translation (via the Parallel Axis Theorem) and rotation of axes using rotation matrices. The inertia matrix can then be determined for simple bodies from tabulated moments of inertia in the principal axes; even for bodies whose moments of inertia can be found only numerically, this procedure allows the inertia tensor to be expressed in arbitrary axes--something particularly important in the analysis of machines, where different bodies' principal axes are virtually never parallel. To understand these principal axes (in which the real, symmetric inertia tensor assumes a diagonalized "normal form"), virtually all of Linear Algebra comes into play. Thus the mathematical field is first reviewed in a rigorous, but easy-to-visualize manner. 3-D rigid body dynamics then become a mere application of the mathematics. Finally analytical mechanics--both Lagrangian and Hamiltonian formulations--is developed, where linear algebra becomes central in linear independence of the coordinate differentials, as well as in determination of the conjugate momenta.Features include:- A general, uniform approach applicable to "machines" as well as single rigid bodies- Complete proofs of all mathematical material. Similarly, there are over 100 detailed examples giving not only the results, but all intermediate calculations- An emphasis on integrals of the motion in the Newtonian dynamics- Development of the Analytical Mechanics based on Virtual Work rather than Variational Calculus, both making the presentation more economical conceptually, and the resulting principles able to treat both conservative and non-conservative systems.

Residual Stress Measurement and the Slitting Method provides complete coverage of the slitting method with new results in analysis, computation and estimation. It discusses different roles of residual stresses from the fracture mechanics perspective. Covering both near-surface and through-thickness residual stress measurements, the book serves as a reference tool for graduate students, researchers and practicing engineers. The authors include discussions on the general expressions for residual stresses acting on the site of a slit, the analysis based on fracture mechanics solutions and finite element computations, the estimations using continuous and piecewise functions with and without least squares fit, examples of residual stress measurement and error analysis, the measurement of stress intensity factors, and many more timely topics. With more than 130 figures, Residual Stress Measurement and the Slitting Method provides detailed formulations and examples of compliance functions, weighted least squares fit and convergence test in stress estimation, and computer programs to facilitate the implementation of the slitting method. This book is an invaluable reference for professionals and researchers in the field.

Stability and Optimization of Structures: Generalized Sensitivity Analysis is the first book to address issues of structural optimization against nonlinear buckling. Through the investigation of imperfection sensitivity, worst imperfection and random imperfection based on concrete theoretical framework, it is shown that optimization against buckling does not necessarily produce an imperfection-sensitive structure. This book offers the reader greater insight into optimization-based and computer-assisted stability design of finite-dimensional structures. Using the unified approach to parameter sensitivity analysis, it connects studies of elastic stability, computational mechanics and applied mathematics. Optimization based on stability theory is presented and explained, with 140 figures to illustrate applications in the framework of finite element analysis. This book serves as an illustrative introduction for professional structural and mechanical engineers, graduate students in engineering, as well as applied mathematicians in the field.

Introduction to Contact Mechanics, Second Edition is a gentle introduction to the mechanics of solid bodies in contact for graduate students, post doctoral individuals, and the beginning researcher.This second edition maintains the introductory character of the first with a focus on materials science as distinct from straight solid mechanics theory. Every chapter has been updated to make the book easier to read and more informative. A new chapter on depth sensing indentation has been added, and the contents of the other chapters have been completely overhauled with added figures, formulae and explanations.The author begins with an introduction to the mechanical properties of materials, general fracture mechanics and the fracture of brittle solids. This is followed by a detailed description of indentation stress fields for both elastic and elastic-plastic contact. The discussion then turns to the formation of Hertzian cone cracks in brittle materials, subsurface damage in ductile materials, and the meaning of hardness. The author concludes with an overview of practical methods of indentation.

Intended for graduate students in mechanical, civil, or structural engineering, or in applied mechanics, this text covers advanced topics in plasticity that have thus far been accessible only in review articles widely scattered through the literature. Practicing engineers will thus also find it a useful reference.This new edition will be completely updated beginning with the fundamentals of the mathematical theory of plasticity, presented in sufficient detail to make the text self- sufficient. The discussion then turns to the theory of plastic stress and its applications to structural analysis and sheet metal forming. This is followed by treatments of axially symmetrical systems and some three-dimensional problems; of the plastic behavior of plates and shells, discussed mainly from the point of view of limit analysis; and of the plasticity of metals with fully developed orthotropic anisotropy and the plastic behavior of anisotropic sheets. The generalized tangent-modulus theory of buckling in the plastic range for columns, plates and shells is treated from the point of view of the bifurcation phenomenon. The concluding chapter deals with a wide range of topics in dynamic plasticity including wave propagation, armor penetration, and structural impact in the plastic range. This new edition includes a full chapter on the Finite Element Method, which appeared in the previous version as an appendix, as well as a large number of homework problems for each chapter. A solutions manual is available for professors.

Preface After15yearssincethepublicationofVibrationofStructuresandMachines and three subsequent editions a deep reorganization and updating of the material was felt necessary. This new book on the subject of Vibration dynamics and control is organized in a larger number of shorter chapters, hoping that this can be helpful to the reader. New materialhas been added and many points have been updated. A larger number of examples and of exercises have been included.

This text aims to impart a sound understanding, both physical and mathematical, of the fundamental theory of vibration and its applications. The book presents in a simple and systematic manner techniques that can easily be applied to the analysis of vibration of mechanical and structural systems. The approach is general, based on the conservation of energy and Lagrangian dynamics, and develops specific techniques from these foundations in clearly understandable stages. Suitable for a one-semester course on vibrations, the book presents concepts in simple terms and explains procedures for solving problems in detail.

This book presents a comprehensive treatment of laminar viscous flow. It thus limits itself to the study flows at small or moderate Reynolds numbers, where the laminar flow is stable, but it also provides a basis for studies of all subsequent extensions, including stability and turbulence. Covering not only the classical topics (the Navier-Stokes equation, exact solutions, and the like), but also topics of great practical importance (lubrication, non-Newtonian properties, heat and mass transfer, and so forth) often left out of standard texts on fluid dynamics, the book will be of use to a broad range of engineers, physicists, and others interested in the flow of viscous fluids.

This text aims to provide practising engineers and researchers with the tools needed to deal with heat transfer in the porous media encountered in geological, environmental, petrochemical and other industrial processes. Tabular and graphic presentations of the results help to connect the fundamental governing and constitutive equations to practical applications. This edition has been corrected and revised, and contains a chapter on computations for two-phase flow.

Fluid flows that transfer heat and mass often involve drops and bubbles, particularly if there are changes of phase in the fluid in the formation or condensation of steam, for example. Such flows pose problems for the chemical and mechanical engineer significantly different from those posed by single-phase flows. This book reviews the current state of the field and will serve as a reference for researchers, engineers, teachers, and students concerned with transport phenomena. It begins with a review of the basics of fluid flow and a discussion of the shapes and sizes of fluid particles and the factors that determine these. The discussion then turns to flows at low Reynolds numbers, including effects due to phase changes or to large radial inertia. Flows at intermediate and high Reynolds numbers are treated from a numerical perspective, with reference to experimental results. The next chapter considers the effects of solid walls on fluid particles, treating both the statics and dynamics of the particle-wall interaction and the effects of phase changes at a solid wall. This is followed by a discussion of the formation and breakup of drops and bubbles, both with and without phase changes. The last two chapters discuss compound drops and bubbles, primarily in three-phase systems, and special topics, such as transport in an electric field.

This text, which is intended to follow the author's Theory of Vibration: An Introduction, aims to further the understanding, both physical and mathematical, of the theory of vibration and its applications, here focusing on discrete and continuous systems. As in the previous volume, the text develops the techniques used to analyze vibrations in mechanical and structural systems from their foundations rationally and in clearly understandable stages. Intended for a graduate course in the theory of vibration, the explanations of procedures and details are easily understandable by students. A new chapter on computer methods for the eigenvalue problem has been added for this edition; it includes discussions of the similarity transformation, generalized eigenvectors, the Jacobi method, the Householder transformation, and QR decomposition.

Intended as an introduction to robot mechanics for students of mechanical, industrial, electrical, and bio-mechanical engineering, this graduate text presents a wide range of approaches and topics. It avoids formalism and proofs but nonetheless discusses advanced concepts and contemporary applications. It will thus also be of interest to practicing engineers. The book begins with kinematics, emphasizing an approach based on rigid-body displacements instead of coordinate transformations; it then turns to inverse kinematic analysis, presenting the widely used Pieper-Roth and zero-reference-position methods. This is followed by a discussion of workplace characterization and determination. One focus of the discussion is the motion made possible by sperical and other novel wrist designs. The text concludes with a brief discussion of dynamics and control. An extensive bibliography provides access to the current literature.

Convective heat transfer is the result of fluid flowing between objects of different temperatures. Thus it may be the objective of a process (as in refrigeration) or it may be an incidental aspect of other processes.Intended for graduate students and for researchers entering the field, this text reviews in a concise and unified manner recent contributions to the principles of convective heat transfer for single and multi-phase systems: It summarizes the role of the fundamental mechanism and the governing differential equations, describes approximation schemes and phenomenological models, and examines their solutions and applications. After a review of the basic physics and thermodynamics, the book divides the subject into three parts. Part 1 deals with single-medium transfers, specifically with intraphase transfers in single-phase flows and with intramedium transfers in two-phase flows. Part 2 deals with fluid-solid transfer processes, both in cases where the interface is small and in cases where it is large, as well as liquid-liquid transfer processes. Part 3 considers three media, addressing both liquid-solid-solid and gas-liquid-solid systems.The emphasis on the presence multiple phases and on energy-conversion mechanisms, such as phase changes or chemical reactions, will make this text a valuable reference for practicing engineers.This new edition has been updated throughout and contains new examples and problems.

Intended for engineers, researchers, and graduate students dealing with materials science, structural design, and nondestructive testing and evaluation, this book represents a continuation of the author's "Fracture Mechanics" (1997). It will appeal to a variety of audiences: The discussion of design codes and procedures will be of use to practicing engineers, particularly in the nuclear, aerospace, and pipeline industries; the extensive bibliography and discussion of recent results will make it a useful reference for academic researchers; and graduate students will find the clear explanations and worked examples useful for learning the field. The book begins with a general treatment of fracture mechanics in terms of material properties and loading and provides up-to-date reviews of the ductile-brittle transition in steels and of methods for analyzing the risk of fracture. It then discusses the dynamics of fracture and creep in homogeneous and isotropic media, including discussions of high-loading-rate characteristics, the behavior of stationary cracks in elastic media under stress, and the propagation of cracks in elastic media.This is followed by an analysis of creep and crack initiation and propagation, describing, for example, the morphology and incubation times of crack initiation and growth and the effects of high temperatures. The book concludes with treatments of cycling deformation and fatigue, creep-fatigue fractures, and crack initiation and propagation. Problems at the end of each chapter serve to reinforce and test the student's knowledge and to extend some of the discussions in the text. Solutions to half of the problems are provided.

This book deals with the computational analysis of thin-walled structures such as aircraft, ships, and containment vessels. Building on the author's earlier book Static and Dynamic Analysis of Structures, it shows how to use computational methods to tackle some of the fundamental problems of structural mechanics, with particular emphasis on nonlinear phenomena. Where the earlier book dealt with linear systems, the central theme running through this volume is the notion that unstable equilibria are associated with motions and large displacements and therefore require a full nonlinear analysis.The discussion begins with an overview of the basic mechanics of deformable bodies, including variational formulations, and then considers the large deflection behavior of shell and frame structures using a finite-element analysis. The second part of the book begins with a summary of linear vibrations of structures, including an introduction to modal analysis; it continues with computational formulations of nonlinear dynamic analyses of structures and refines the concept of dynamic equilibrium in the context of large deflections.The book concludes with a discussion of stability, including the difficult problem of stability of motions in the large.By describing the methods on which commercial software pakckages are based, this book allows an engineer to evaluate the results these computations produce. It therefore should be useful to practicing engineers and graduate students.

This thoroughly revised and updated edition of the classic text on surface mechanics preserves the objectives of the original: the rigorous derivation of surface properties such as temperature and deformation from the differential equations of continuum mechanics. From such solutions for the surfaces of single bodies one can then formulate problems involving two bodies at rest or in relative motion in terms of a singular integral equation. The discussion is analytical and theoretical, but animated by the authors' decades of experience in applications and experimental mechanics. This new edition has been updated to include many technologically motivated problems and solutions, especially computer solutions. Beginning with a survey of the field equations of classical continuum mechanics, the book continues with a discussion of surface temperatures in moving bodies. It then turns to semi-infinite and layered elastic media, discussing stress and deformation as well as thermal stress and associate deformation fields. Treatments of viscoelasticity and perfect plasticity concentrate on semi-infinite solids; these are followed by a discussion of rough surfaces.The book concludes with a lengthy chapter of applications. An appendix discusses integral equations. Intended for graduate students of mechanics and mechanical engineering, the book will also be of interest to applied mathematicians and others interested in tribology.
