Opis

The goal in optimal shape design is to computerize the design process for structural systems by determining the shape of the structure. The mathematical basis of optimal shape design, finite element approximation and numerical realization by the application of optimization techniques, are the subject of this book. Additions to this second, revised edition include CAD examples and engineering applications, development of computational aspects such as design sensitivity analysis and algorithmization, and contact shape optimization.

This book addresses the formulation, approximation and numerical solution of optimal shape design problems: from the continuous model through its discretization and approximation results, to sensitivity analysis and numerical realization. Shape optimization of structures is addressed in the first part, using variational inequalities of elliptic type. New results, such as contact shape optimization for bodies made of non–linear material, sensitivity analysis based on isoparametric technique, and analysis of cost functionals related to contact stress distribution are included. The second part presents new concepts of shape optimization based on a fictitious domain approach. Finally, the application of the shape optimization methodology in the material design is discussed. This second edition is a fully revised and up–dated version of Finite Element Method for Optimal Shape Design. Numerous numerical examples illustrate the theoretical results, and industrial applications are given.
