Model Analysis of Plane Structures deals with simple techniques of analysis plane structures with the aid of scale models. Model analysis of the kind considered herein is a means of replacing the numerical work of formal structural analysis by mechanical operations. It utilizes the same assumptions as formal analysis and offers nothing more in the end-product, but the user gains unique insight into structural behavior. The book begins with a discussion of early approaches to systematic model analysis and the limitations and accuracy of model analysis. This is followed by separate chapters on the approach to flexural similarity, which consists essentially of determining directly the conditions for the properties of deformation of two geometrically similar structures to be similar; the theory of indirect model analysis; and models of frame networks. The final two chapters deal with the use of models for indirect analysis and direct analysis, respectively; these conclude with sample problems to enable readers to test their understanding of the subject matter.

Cartesian Tensors in Engineering Science provides a comprehensive discussion of Cartesian tensors. The engineer, when working in three dimensions, often comes across quantities which have nine components. Variation of the components in a given plane may be shown graphically by a familiar construction called Mohr''s circle. For such quantities it is always possible to find three mutually perpendicular axes, called principal axes, with respect to which the six ""paired up"" components are all zero. Such quantities are called symmetric tensors of the second order. The student may at this stage be struck by the fact that the physical quantities with which he normally deals have either one component, three components or nine components, being respectively scalars, vectors, and what have just been called second order tensors. The family of quantities having 1, 3, 9, 27, … components does exist. It is the tensor family in three dimensions. The book discusses the ""tests"" a given quantity must pass in order to qualify as a member of the family. The products of tensors, elasticity, and second moment of area and moment of inertia are also covered. Although written primarily for engineers, it is hoped that students of various branches of physical science may find this book useful.

Elementary Theory of Elastic Plates deals with plate theory, particularly on the elastic behavior of initially flat thin plates subjected to loads, producing deflexions. This book discusses rectangular plates and circular plates subjected to different types of load conditions. This text describes the bending moment and curvature of beams, and gives the formula of principal axes, where the location of a neutral axis that experiences zero stress and strain, can be found. This book also notes how calculations can show small or negligible deflexions. The text discusses Possion''s ratio effect and the Mohr''s circle relationship. This text analyzes the various loads acting on different parts of the rectangular plate using the Navier method; the Levy''s method is taken up when considerations are on other forms of boundary support on the rectangular plate. This book then addresses the circular plate that experiences bending moments and curvatures when it is placed under radially symmetric loads. This text explains the equation that is applicable in a radially symmetric case. This book also addresses understanding approximations of energy in stability problems when there is bending and twisting as shown in a strut with a certain thickness, radial length of the arms, and length of the strut. Engineers, physicists, architects, and designers of industrial equipment subject to heavy loads will appreciate the information found in this book.

The Mechanical Behaviour of Engineering Materials aims to relate properties and structure, and to provide a theoretical basis upon which to extrapolate when conditions or materials outside previous experience arise. The present text refers primarily to metals and alloys, other (non-crystalline) solids are treated rather less fully. This is largely dictated by the state of knowledge at the present time, for although there is a large mass of data concerning the properties of non-metallic materials, much of this is empirical and a full explanation is made difficult by the complexities of an irregular initial structure. The book can be divided into the three sections covering constitution, properties, and significance of test data. Separate chapters discuss properties such as heterogeneity, elasticity, plasticity, and fracture. Subsequent chapters deal with tensile and hardness tests; creep, fatigue and impact tests; and the selection of engineering materials. Throughout the text the author has endeavored to confine the discussion to those aspects of materials science which appear to be reasonably well understood at the present time.

Plastic Theory of Structures focuses on the use of plastic theory in design and shows how code requirements are related to theoretical considerations. More specifically, the effect of axial load and shear force on plastic moment capacity is examined, along with biaxial bending, frame and local instability, and the use of partial load factors. The significance of repeated loading in plastic design is also highlighted. Comprised of six chapters, this book begins with an overview of plastic failure and the behavior beyond the elastic limit (with particular emphasis on the failure loads) of structures in which resistance to bending action is the primary means by which the loads are supported. Attention is paid to how the collapse load factor of a given structure may be derived, that is, the structure has been analyzed in relation to plastic collapse. The reader is then introduced to methods of plastic analysis; plastic moments under shear force and axial load; and minimum weight design. The book also considers variable repeated loading before concluding with a chapter on stability and the influence of various structural parameters and appropriate methods for the estimation of failure loads. This monograph will be of interest to civil and structural engineers.
