PRINCIPLES OF CONTINUUM MECHANICS
A Study of Conservation Principles with Applications
As most modern technologies are no longer discipline-specific but involve multidis-
ciplinary approaches, undergraduate engineering students should be introduced to
the principles of mechanics so that they have a strong background in the basic prin-
mon to all disciplines and are able to work at the interface of science and
engineering disciplines. This textbook is designed for a first course on principles of
mechanics and provides an introduction to the basic concepts of stress and strain and
conservation principles. It prepares engineers and scientists for advanced courses in
traditional as well as emerging fields such as biotechnology, nanotechnology, energy
systems, putational mechanics. This simple book presents the subjects of
mechanics of materials, fluid mechanics, and heat transfer in a unified form using the
conservation principles of mechanics.
J. N. Reddy is a Distinguished Professor and holder of the Oscar S. Wyatt Endowed
Chair in the Department of Mechanical Engineering at Texas A&M University
(l).
Dr. Reddy is a renowned researcher and educator in the broad fields of mechanics,
applied mathematics, putational engineering science. Dr. Reddy’s research
areas include theory and finite element analysis of problems in structural mechanics
(composite plates and shells), fluid dynamics, and heat transfer; theoretical model-
ing of stress and deformation of biological cells and soft tissues; posites;
and development of putational technology (including the K-version finite
element models based on the least-squares method in collaboration with Professor
Karan Surana of the University of Kansas). He is the author of more than 400 journal
papers and 16 books on these subjects. His books include Mechanics of Laminated
Plates and Shells: Theory and Analysis, Second Edition, 2004; An Introduction to
Nonlinear Finite Element An
