This book develops a modern presentation of Continuum Mechanics, oriented towards numerical applications in the fields of nonlinear analysis of solids, structures and fluid mechanics. The kinematics of the continuum deformation, including pull-back / push-forward transformations between different configurations, stress and strain measures, balance principles, constitutive relations and variational principles are developed using general curvilinear coordinates. Even though the mathematical presentation of the different topics is quite rigorous, an effort is made to link formal developments with engineering physical intuition.

Geared toward undergraduate and graduate students, this text extends applications of the finite element method from linear problems in elastic structures to a broad class of practical, nonlinear problems in continuum mechanics. It treats both theory and applications from a general and unifying point of view. The text reviews the thermomechanical principles of continuous media and the properties of the finite element method, and then brings them together to produce discrete physical models of nonlinear continua. The mathematical properties of these models are analyzed, along with the numerical solution of the equations governing the discrete model. Though the theory and methods are sufficiently general to be applied to any nonlinear problem, emphasis has been placed on problems in finite elasticity, viscoelasticity, heat conduction, and thermoviscoelasticity. Problems in rarefied gas dynamics and nonlinear partial differential equations are also examined. Other topics include topological properties of finite element models, applications to linear and nonlinear boundary value problems, and discrete models of nonlinear thermomechanical behavior of dissipative media. This comprehensive text is valuable not only to students of structural analysis and continuum mechanics but also to professionals researching the numerical analysis of continua

This volume consists of a collection of chapters by recognized experts to provide a comprehensive fundamental theoretical continuum treatment of constitutive laws used for modelling the mechanical and coupled-field properties of various types of solid materials. It covers the main types of solid material behaviour, including isotropic and anisotropic nonlinear elasticity, implicit theories, viscoelasticity, plasticity, electro- and magneto-mechanical interactions, growth, damage, thermomechanics, poroelasticity, composites and homogenization. The volume provides a general framework for research in a wide range of applications involving the deformation of solid materials. It will be of considerable benefit to both established and early career researchers concerned with fundamental theory in solid mechanics and its applications by collecting diverse material in a single volume. The readership ranges from beginning graduate students to senior researchers in academia and industry.

This book is an outcome of academic cooperation between the Volgograd State University of Architecture and Civil Engineering in Russia, Stellenbosch University in South Africa and the Technische Universit„t Berlin in Germany. The authors performed coordinated and cooperative research on nonlinear structural analysis and on computer-supported civil engineering over a period of several years. Many of the innovative aspects of this book were invented and developed in the course of the research effort.

In 1969 scientists came together for the first time to discuss problems of instability of continuous systems on a IUTAM - Symposium. Since then twelve years of a fast and interesting development in the field of stability have passed. Therefore it was necessary to arrange a meeting for scientists again in order to exchange experiences and opinions about this topic. In 1978 the Bureau of IUTAM asked me to become chairman of the scientific committee of the Second IUTAM Symposium on Stability in the Mechanics of Continua and to organize this meeting. The following scientists have been appointed as members of this scientific committee: Prof. T. B. Benjamin University of Oxford, Mathematical Institute Oxford, GB Prof. V. V. Bolotin USSR Academy of Science, Mechanical Engineering Research Institute, Moscow, USSR Prof. J. W. Hutchinson Harvard University, Division of Applied Sciences Cambridge, USA Prof. K. Kirchgassner Universitat Stuttgart, Mathematisches Institut A Stuttgart, FRG Prof. A. Kulikovsky Mechanics National Committee Moscow, USSR VI Prof. H. H. E. Leipholz University of Waterloo, Department of Civil Engineering Waterloo, Canada Prof. R. C. Di Prima Rensselaer Poly technical Institute, Department of Mathematical Science, Troy, USA The symposium took place in Nlimbrecht near Cologne from th th August the 31 to September the 4 , 1981 and it dealt with both solid and fluid continua. The following volume contains the lectures in the succession as they were held during the symposium, devided into two parts: 1.
