Although there are several books in print dealing with elasticity, many focus on specialized topics such as mathematical foundations, anisotropic materials, two-dimensional problems, thermoelasticity, non-linear theory, etc. As such they are not appropriate candidates for a general textbook. This book provides a concise and organized presentation and development of general theory of elasticity. This text is an excellent book teaching guide.

Key Features

  • Contains exercises for student engagement as well as the integration and use of MATLAB Software
  • Provides development of common solution methodologies and a systematic review of analytical solutions useful in applications of


graduate students, engineering industries and governmental research centers

Table of Contents

Part I: Foundations and Elementary Applications (Part I - the first half of the text, provides a standard first semester course in beginning elasticity theory and applications. Particular topics from Part II could also be used to supplement such a first course.)<BR id=""CRLF""><BR id=""CRLF"">1. Mathematical Preliminaries (A self-contained review is provided of mathematical principles and notation needed in the text. This material can be covered at the beginning of the course to bring the entire class to a common point or various sections can be referred to as later course material is presented. Vector and index notation is introduced and Cartesian tensor notation will become the primary notational scheme for the formulation part of the course. MATLAB is first introduced here and is used to conduct rotational transformations and solve eigenvalue problems.)<BR id=""CRLF"">1.1 Introduction<BR id=""CRLF"">1.2 Scalar, Vector and Matrix Notation<BR id=""CRLF"">1.3 Index Notational Properties<BR id=""CRLF"">1.4 Kronecker Delta and Alternating Symbol<BR id=""CRLF"">1.5 Determinants<BR id=""CRLF"">1.6 Coordinate Rotation Transformations (This section is the first MATLAB application, <BR id=""CRLF"">and a specific code is to be introduced for coordinate rotations. This will reinforce the theoretical material presented and allow students to explicitly calculate particular transformations and evaluate the nature of this concept.)<BR id=""CRLF"">1.7 Cartesian Tensors<BR id=""CRLF"">1.8 Principal Values, Axes and Invariants of Symmetric Second Order Tensors<BR id=""CRLF"">(Another MATLAB application is covered, which will solve the general eigenvalue problem. This will again reinforce the theoretical material covered in this section.)<BR id=""CRLF"">1.9 Algebra of Cartesian Tensors<BR id=""CRLF"">1.10 Tensor Fields, Derivatives and Integral Theorems<BR id=""CRLF"">1.11 Orthogonal Curvilinear Coordinates<BR id=""CRLF""><BR id=""CRLF"">2. Deformation: Displacements and Strains (Starting with a brief presentation of general deformation theory, the chapter moves into small deformation kinematics, and develops basic definitions and relations for linear elasticity.) <BR id=""CRLF"">2.1 Introduction<BR id=""CRLF"">2.2 General Deformations<BR id=""CRLF"">2.3 Small Deformation Theory - Strain-Displacement Relations<BR id=""CRLF"">2.4 Principal Strains<BR id=""CRLF"">2.5 Deviatoric Strains<BR id=""CRLF"">2.6 Strain Compatibility<BR id=""CRLF"">2.7 Strain Transformation (MATLAB applications from sections 1.6 and 1.8 are applied to specific strain transformation problems. Applications related to strain measurement systems will be included.)<BR id=""CRLF""><BR id=""CRLF"">3. Stress and Equilibrium (This chapter will cover the appropriate theory for force and stress distribution in solids undergoing small deformation.)<BR id=""CRLF""> 3.1 Introduction<BR id=""CRLF"">3.2 Body and Surface Forces<BR id=""CRLF"">3.3 The Traction Vector<BR id=""CRLF"">3.4 The Stress Tensor<BR id=""CRLF"">3.5 Principal Stresses<BR id=""CRLF"">3.6 Deviatoric Stresses<BR id=""CRLF"">3.7 Stress Transformation (Similar to section 2.7, MATLAB applications will be introduced for specific stress transformation problems)<BR id=""CRLF"">3.8 Equilibrium Equations<BR id=""CRLF""><BR id=""CRLF"">4. Material Behavior-Constitutive Equations (The chapter introduces linear elastic material behavior as formalized by Hooke's Law. The formulation starts with the general case, pointing out the complexities for heterogeneous anisotropic materials. Further more detailed study of anisotropic elasticity is made in chapter 11. Reduction for homogeneous and isotropic materials is then made. Thermoelastic relations are initially presented, and further applications of this case are made in chapter 12. Discussion of bounds on elastic constants is saved for chapter 6 where strain energy is introduced.)<BR id=""CRLF"">4.1 Introduction<BR id=""CRLF"">4.2 Generalized Hooke's Law<BR id=""CRLF"">4.3 Isotropic Case<BR id=""CRLF"">4.4 Thermoelastic Relations<BR id=""CRLF"">4.5 Material Characterization <BR id=""CRLF"">4.6 Physical Data (In order to provide students with some experience of real materials, this section will present tables of elastic constants for common materials used in engineering applications.)5. Formulation and Solution Strategies (This chapter is very important for student understanding of theory and application for problem solution. I feel that I have provided more educational innovation than found in competitor texts. Collecting and understanding all of the previous theory and equations is not an easy task for students. Developing the final formulations will be done concisely and organized around solution strategies. Material in section 5.7 will provide useful material that will link with later chapters in the text.) <BR id=""CRLF"">5.1 Introduction<BR id=""CRLF"">5.2 Boundary Conditions and Fundamental Problem Classifications (Some additional material is presented here to provide students with more experience on proper formulation of boundary conditions, since this has been a perceived area of student difficulty)<BR id=""CRLF"">5.3 Stress Formulation (Stress function solution strategy is discussed)<BR id=""CRLF"">5.4 Displacement Formulation (Displacement potential solution strategy is mentioned)<BR id=""CRLF"">5.5 Principal of Superposition<BR id=""CRLF"">5.6 Saint-Venant's Principle<BR id=""CRLF"">5.7 General Solution Strategies (This particular section will contain special extended discussions on solution strategies in order to provide students with a more broad and general understanding of the variety of such techniques. Many of these solution methods will then be explicitly demonstrated in appropriate problems in later chapters. Students wishing to apply elasticity theory to their own future work will need such information to make a successful solution method choice.)<BR id=""CRLF""><BR id=""CRLF"">- Direct Method<BR id=""CRLF"">Example 5.1 Stretching of Prismatic Bar Under Its Own Weight<BR id=""CRLF"">- Inverse Method<BR id=""CRLF"">Example 5.2 Pure Beam Bending <BR id=""CRLF"">- Semi_Inverse Method<BR id=""CRLF"">Example 5.3 Torsion of Prismatic Bars<BR id=""CRLF""> - Analytical Solution Procedures<BR id=""CRLF"">Power Series, Fourier Methods, Integral Transform and Complex Variable<BR id=""CRLF"">Techniques<BR id=""CRLF""> - Approximate Solution Procedures<BR id=""CRLF"">Ritz Technique<BR id=""CRLF""> - Numerical Solution Procedures<BR id=""CRLF"">Finite Difference, Finite and Boundary Element Techniques<BR id=""CRLF""><BR id=""CRLF"">6. Strain Energy and Related Principles (Final elasticity formulation is completed in this chapter through the introduction of strain energy and related topics. Standard uniqueness and bounds on elastic moduli are discussed. The reciprocal theorem is presented and this will lead into the integral formulation that is later used in developing the numerical boundary element method in chapter 15.)<BR id=""CRLF"">6.1 Introduction<BR id=""CRLF"">6.2 Strain Energy<BR id=""CRLF"">6.3 Uniqueness of the Elasticity Boundary-Value Problem<BR id=""CRLF"">6.4 Bounds on the Elastic Constants<BR id=""CRLF"">6.5 Reciprocal Theorem<BR id=""CRLF"">6.6 Integral Formulation of Elasticity: Somigliana's Identity<BR id=""CRLF"">6.7 Principle of Virtual Work <BR id=""CRLF"">6.8 Principles of Minimum Potential and Complimentary Energy<BR id=""CRLF"">6.9 Ritz Method<BR id=""CRLF""><BR id=""CRLF"">7. Two-Dimensional Formulations (This chapter establishes the standard two-dimensional theories of plane strain, plane stress and generalized plane stress. The Airy stress function solution methodology is covered, and is latter used to develop several analytical solutions in chapter 8.)<BR id=""CRLF"">7.1 Introduction<BR id=""CRLF"">7.2 Plane Strain<BR id=""CRLF"">7.3 Plane Stress<BR id=""CRLF"">7.4 Generalized Plane Stress<BR id=""CRLF"">7.5 Airy Stress Function<BR id=""CRLF"">7.6 Polar Coordinate Formulation<BR id=""CRLF""><BR id=""CRLF"">8. Two-Dimensional Problem Solution (Numerous analytical solutions are developed in this chapter. In order to provide comparisons with student's previous knowledge and experience, particular stress and displacement solutions are compared with elementary mechanics of materials solutions. Continued use of MATLAB software is made in many examples to evaluate and plot the analytical stress and displacement solution fields. This is accomplished through the use of X-Y, polar and contour plots as illustrated in Figures 8.4, 8.5, 8.13, 8.22, and 8.36. A unique feature of this activity is the plotting of maximum shear stress contours and the subsequent comparison with the corresponding photoelastic fringe patterns. This is done in Figure 8.36 and in exercises 8-18 and 8-20. It is felt that students will appreciate and understand more clearly such solutions when they are able to view such graphical representations. This concept also fits nicely with the numerical solution procedures presented in chapter 15.)<BR id=""CRLF"">8.1 Introduction<BR id=""CRLF"">8.2 Cartesian Coordinate Solutions Using Polynomials<BR id=""CRLF""> Example 8.1 Uniaxial Tension of a Beam<BR id=""CRLF""> Example 8.2 Pure Bending of a Beam<BR id=""CRLF""> Example 8.3 Bending of a Beam by Uniform Transverse Loading<BR id=""CRLF"">8.3 Cartesian Coordinate Solutions Using Fourier Methods<BR id=""CRLF""> Example 8.4 Beam Subjected to Transverse Sinusoidal Loading<BR id=""CRLF""> Applications Involving Fourier Series<BR id=""CRLF""> Example 8.5 Rectangular Domain with Arbitrary Boundary Loading<BR id=""CRLF"">8.4 General Solutions in Polar Coordinates<BR id=""CRLF""> - Axisymmetric Solution<BR id=""CRLF""> - Mitchell Solution<BR id=""CRLF"">8.5 Polar Coordinate Solutions<BR id=""CRLF""> Example 8.6 Thick-Walled Cylinder Under Uniform Boundary Pressure<BR id=""CRLF""> Pressurized Hole in an Infinite Medium<BR id=""CRLF""> Stress Free Hole in an Infinite Medium Under Uniform Tension at Infinity<BR id=""CRLF""> Example 8.7 Infinite Medium with a Stress Free Hole Under Uniform Far Field <BR id=""CRLF""> Loading<BR id=""CRLF""> Biaxial and Shear Loading Cases<BR id=""CRLF""> Example 8.8 Wedge and Semi-Infinite Domain Problems<BR id=""CRLF""> Quarter Plane Example<BR id=""CRLF""> Half Space Examples<BR id=""CRLF""> Half Space Under Uniform Normal Stress Over x [0<BR id=""CRLF""> Half Space Under Concentrated Force at the Origin (Flamant Solution)<BR id=""CRLF""> Half Space Under a Surface Concentrated Moment<BR id=""CRLF""> Half Space Under Uniform Normal Loading Over -a / x / a<BR id=""CRLF""> Notch and Crack Problems<BR id=""CRLF""> Example 8.9 Curved Beam Problems<BR id=""CRLF""> Pure Bending Example<BR id=""CRLF""> Curved Cantilever Under End Loading<BR id=""CRLF""> Example 8.10 Disk Under Diametrical Compression<BR id=""CRLF""> Example 8.11 Rotating Disk Problem<BR id=""CRLF""><BR id=""CRLF"">9.

Complex Variable Methods (This chapter provides an overview of complex variable methods for solution of two-dimensional elasticity problems. A brief mathematical review of complex variable theory is provided within the chapter. Formulation and solution schemes are based on using Kolosov-Muskhelishvili complex potentials. Applications include examples of stress concentration and fracture mechanics (previously introduced in example 8.8).

Anisotropic Elasticity (This chapter picks up from the material in section 4.2 and presents a concise development of elasticity applied to anisotropic materials. After a brief description of a torsion example, the chapter focuses primarily on two-dimensional applications using the complex potentials as introduced in the preceding chapter.

Thermoelasticity (Starting from the introductory material in section 4.4, this chapter provides a brief formulation of thermoelasticity and solution of problems of engineering interest. Most of the application problems are to be two-dimensional, and examples will be solved using methods previously discussed in chapters 8, 10 and 11. As in previous chapters, examples of stress concentration and fracture mechanics will be presented.)<BR id=""CRLF"">12.1 Introduction<BR id=""CRLF"">12.2 Heat Conduction and the Energy Equation<BR id=""CRLF"">12.3 General Uncoupled Formulation<BR id=""CRLF"">12.4 Two-Dimensional Formulation<BR id=""CRLF"">- Plane Strain<BR id=""CRLF"">- Plane Stress<BR id=""CRLF"">12.5 Displacement Potential Solution<BR id=""CRLF"">12.6 Stress Function Formulation<BR id=""CRLF""> Example 12.1 Thermal Stresses in an Elastic Strip<BR id=""CRLF"">12.7 Polar Coordinate Formulation<BR id=""CRLF"">12.8 Radially Symmetric Problems<BR id=""CRLF""> Example 12.2 Circular Plate Problems<BR id=""CRLF"">12.9 Complex Variable Methods for Plane Problems<BR id=""CRLF""> Example 12.3 Annular Plate Problem<BR id=""CRLF""> Example 12.4 Stresses Around a Circular Hole in an Infinite Plane Under <BR id=""CRLF""> Uniform Heat Flow<BR id=""CRLF""> Example 12.5 Stresses Around an Elliptical Hole in an Infinite Plane Under<BR id=""CRLF""> Uniform Heat Flow<BR id=""CRLF""><BR id=""CRLF"">13.

This book is a welcome addition to the set of textbooks available to beginning graduate students and advanced undergraduates in mechanical engineering. I have previously taught the subject of elasticity from textbooks written by Barber, Salughter, and Shames with frequent references to the classics by Timoshenko, Love, Sokolnikoff, and Green and Zerna. However, students have found these books either too difficult to understand or too dated in their notation. When I received the new textbook by Professor Sadd, I read it briefly and then handed it over to one of my graduate students who was preparing for his qualifying examinations. His response was unqualified admiration of the ease with which he was able to navigate the book and grasp its contents. - Biswajit Banerjee - Department of Mechanical Engineering, University of Utah
