A practical approach to the computational methods used to solve real-world dynamics problems
Computational dynamics has grown rapidly in recent years with the advent of high-speed digital computers and the need to develop simulation and analysis computational capabilities for mechanical and aerospace systems that consist of interconnected bodies.
Computational Dynamics, Second Edition offers a full introduction to the concepts, definitions, and techniques used in multibody dynamics and presents essential topics concerning kinematics and dynamics of motion in two and three dimensions.
Skillfully organized into eight chapters that mirror the standard learning sequence of computational dynamics courses, this Second Edition begins with a discussion of classical techniques that review some of the fundamental concepts and formulations in the general field of dynamics. Next, it builds on these concepts in order to demonstrate the use of the methods as the foundation for the study of computational dynamics. Finally, the book presents different computational methodologies used in the computer-aided analysis of mechanical and aerospace systems.
Each chapter features simple examples that show the main ideas and procedures, as well as straightforward problem sets that facilitate learning and help readers build problem-solving skills.
Clearly written and ready to apply, Computational Dynamics, Second Edition is a valuable reference for both aspiring and practicing mechanical and aerospace engineers.
Review from a User on Amazon.com
This is a great book. Very well written and easy to follow. I bought this because I wanted to know how to implement a constrained Newtonian physics engine. This book provided almost everything I needed to know.

Since the first edition of this book was published, there have been major improvements in symbolic mathematical languages such as Maple and Mathematica and this has opened up the possibility of solving considerably more complex and hence interesting and realistic elasticity problems as classroom examples. It also enables the student to focus on the formulation of the problem (e.g. the appropriate governing equations and boundary conditions) rather than on the algebraic manipulations, with a consequent improvement in insight into the subject and in motivation. During the past 10 years I have developed files in Maple and Mathematica to facilitate this process, notably electronic versions of the Tables in the present Chapters 19 and 20 and of the recurrence relations for generating spherical harmonics. One purpose of this new edition is to make this electronic material available to the reader through the Kluwer website . I hope that readers will make use of this resource and report back to me any aspects of the electronic material that could benefit from improvement or extension. Some hints about the use of this material are contained in Appendix A. Those who have never used Maple or Mathematica will find that it takes only a few hours of trial and error to learn how to write programs to solve boundary value problems in elasticit

Energy Methods in Applied Mechanics by Henry L. Langhaar
The book has been planned for a two-semester course in advanced mechanics for graduate students. In addition, it may be used for independent study and for reference purposes. A_ sound course in advanced calculus, the rudiments of Gibb's vector theory, some knowledge of
advanced strength of materials, and the fundamentals of elasticity, theory are prerequisites. The student who has mastered these subjects will not find the mathematics too difficult.
Energy Methods in Applied Mechanics was developed from class notes used in a graduate course at the University of Illinois for about ten years. I have sustained an interest in energy principles of mechanics for more than twenty years through my research efforts, teaching activities, and employment as a structural research engineer. I am pleased to acknowledge as a
notable source of information the inspiring lectures on variational principles of mechanics by Š” Lanczos at Purdue University during 1940 and 1941.

Introduction to Continuum Mechanics by Micheal Lai,David Rubin and Erhard Krempl
The first edition of this book was published in 1974, nearly twenty years ago. It was written as a text book for an introductory course in continuum mechanics and aimed specifically at the junior and senior level of undergraduate engineering curricula which choose to introduce to the students at the undergraduate level the general approach to the subject matter of continuum mechanics. We are pleased that many instructors of continuum mechanics have found this little book serves that purpose well. However, we have also understood that many instructors have used this book as one of the texts for a beginning graduate course in continuum mechanics. It is this latter knowledge that has motivated us to write this new edition. In this present edition, we have included materials which we feel are suitable for a beginning graduate course in continuum mechanics.
Contents
Chapter 1 Introduction
Chapter 2 Tensors
Chapter 3 Kinematics of a Continuum
Chapter 4 Stress
Chapter 5 The Elastic Solid
Chapter 6 Newtonian Viscous Fluid
Chapter 7 Integral Formulation of General Principles
Chapter 8 Non-Newtonian Fluids
the books gives detailed information on tensor analysis and many formulation makes them simpler to understand . this is a very good book for students studying elasticity, plasticity and solid mechanics or CFD

This book is an exposition of the dynamic theory of thin walled linearly elastic bodies, treated as an asymptotic branch of 3D elasticity free of ad hoc assumptions. Its most important feature is that it takes into consider- consideration phenomena characterized by the wavelength having the order of the thickness of a body and by the time scale of the order of the time elastic waves take to propagate the distance equal to the thickness. It is evident that the classical Kirchhoff-Love theory of shells, as well as its refinements, are not applicable for describing such phenomena. The main part of the book deals with the derivation of asymptotic approximations of the 3D dynamic equations of elasticity as the thickness tends to zero.
