Summary

This book offers a broad overview of the potential of continuum mechanics to describe a wide range of macroscopic phenomena in real-world problems. Building on the fundamentals presented in the authors’ previous book Continuum Mechanics using Mathematica, this new work explores interesting models of continuum mechanics having applications in a wide variety of fields.Specific topics covered include:* various aspects of nonlinear elasticity, including equilibrium equations and their variational formulation, nonlinear constitutive equations, existence and uniqueness theorems of Van Buren and Stoppelli, and Signorini's method with some extensions to live loads and acceleration waves* continua with directors* a model of a continuum with a nonmaterial moving interface* mixture theory (The Gibbs Rule in a binary mixture)* interaction between electric or magnetic fields with matter* micromagnetism* continua in special relativity and relativistic interactions between matter and electromagnetic fieldsMathematica® notebooks accompanying the text are available for download at http://www/birkhauser.com/978-0-8176-4869-5. Aimed at advanced graduate students, applied mathematicians, mathematical physicists, and engineers, the work will be an excellent self-study reference or supplementary textbook in graduate-level courses focusing on advanced topics and research trends in continuum mechanics.
