Overview

This book presents some mathematical methods used in the study of initial and boundary problems for Bingham fluids and rate-depedent viscoplasticity. Existence and uniqueness results are presented and the behaviour of the solution with respect to the data is also studied. For some problems, the numerical approximation of the solution is also given and numerical results are presented. Elliptic variational inequalities, convex functions, monotone operators, semigroups of operators, and nonlinear evolution equations are used as mathematical instruments. The book presents a sudy of some problems of viscoplasticity using various and different mathematical methods, the mathematical results are interpreted from a mathematical point of view, and the theory is developed to deal with numerical results from possible applications in industry and technology.

<br> An excellent development of semi-linear rate dependent models from a rigorous mathematical viewpoint, a link missing in many engineering descriptions of viscoplastic behavior....Could be the text, in conjunction with sources of more epxperimental data, for a course in viscoplasticity. Within the parameters it sets for itself, the book is self contained and accessible to many readers. --Applied Mechanics Reviews<p><br> A valuable summary of the state of a theory that seems to be fairly mature, and it will be a useful reference to researchers in this area of continuum mechanics. --Mathematical Reviews Clippings 95e<p><br> Its contents reflect extensions of original research work of the authors, and are addressed to students and researchers interested in the mathematical and numerical problems of nonlinear mechanics and its extensions; they cover the gamut from the formulation of the mathematical model to its numerical solution. --Quarterly of Applied Mathematics<p><br>
