Summary:This book presents necessary background knowledge on mechanics to understand and analyze elastic wave propagation in solids and fluids. This knowledge is necessary for elastic wave propagation modeling and for interpreting experimental data generated during ultrasonic nondestructive testing and evaluation (NDT&E). The book covers both linear and nonlinear analyses of ultrasonic NDT&E techniques. The materials presented here also include some exercise problems and solution manual. Therefore, this book can serve as a textbook or reference book for a graduate level course on elastic waves and/or ultrasonic nondestructive evaluation. It will be also useful for instructors who are interested in designing short courses on elastic wave propagation in solids or NDT&E.

The materials covered in the first two chapters provide the fundamental knowledge on linear mechanics of deformable solids while Chapter 4 covers nonlinear mechanics. Thus, both linear and nonlinear ultrasonic techniques are covered here. Nonlinear ultrasonic techniques are becoming more popular in recent years for detecting very small defects and damages. However, this topic is hardly covered in currently available textbooks. Researchers mostly rely on published research papers and research monographs to learn about nonlinear ultrasonic techniques. Chapter 3 describes elastic wave propagation modeling techniques using DPSM. Chapter 5 is dedicated to an important and very active research field – acoustic source localization – that is essential for structural health monitoring and for localizing crack and other type of damage initiation regions.

Features• Introduces Linear and Nonlinear ultrasonic techniques in a single book. • Commences with basic definitions of displacement, displacement gradient, traction and stress.• Provides step by step derivations of fundamental equations of mechanics as well as linear and nonlinear wave propagation analysis.• Discusses basic theory in addition to providing detailed NDE applications.• Provides extensive example and exercise problems along with an extensive solutions manual.

Although there are many books on the finite element method (FEM) on the market, very few present its basic formulation in a simple, unified manner. Furthermore, many of the available texts address either only structure-related problems or only fluid or heat-flow problems, and those that explore both do so at an advanced level.Introductory Finite Element Method examines both structural analysis and flow (heat and fluid) applications in a presentation specifically designed for upper-level undergraduate and beginning graduate students, both within and outside of the engineering disciplines. It includes a chapter on variational calculus, clearly presented to show how the functionals for structural analysis and flow problems are formulated. The authors provide both one- and two-dimensional finite element codes and a wide range of examples and exercises. The exercises include some simpler ones to solve by hand calculation-this allows readers to understand the theory and assimilate the details of the steps in formulating computer implementations of the method.Anyone interested in learning to solve boundary value problems numerically deserves a straightforward and practical introduction to the powerful FEM. Its clear, simplified presentation and attention to both flow and structural problems make Introductory Finite Element Method the ideal gateway to using the FEM in a variety of applications.

This book covers the latest advances in the popular research areas in Earthquake Engineering: Seismic Protection, Non-Destructive Testing and Structural Health Monitoring, as well as Seismic Performance Assessment. Part I includes seven chapters on seismic protection systems, a new passive isolation system for tower structures, frictional base isolation systems, period changeable isolation systems and presented applications, and recent developments in Italy, Japan and Macedonia. Also, particularities of design basis ground motion for long period structures are explained. Soil-Structure interaction models on the relevant subject are presented by classifying them. Part II presents three chapters on the new developments on Non-Destructive Testing (NDT) and Structural Health Monitoring (SHM) for Performance Assessment of Structures. Applications and recent developments in USA, Canada, and Turkey are presented. Part III includes eight chapters on Seismic Performance Assessment. The subject of this part is presented on its following important components, and results are discussed: New criterion on performance based seismic design with application to a high-rise building; seismic design and performance assessment of a super tall concrete core wall building; seismic design and evaluation of high-performance modular tall timber building; challenges to detailed finite element analysis of entire building structures; seismic performance evaluation of traditional Japanese wooden houses with outer-frame reinforcement; dynamic response of pipeline, subjected to subsurface and surface blast explosion; bond behavior of sand-coated CFRP rebar embedded in concrete are given; seismic resistant large-span shell structures are presented. 

The book presents a concise summary of latest research findings, and will be of interest to a wide range of professionals in earthquake engineering, including graduate students, instructors, designers, and researches.
