Finite Element Approximation for Optimal Shape Design: Theory and ApplicationsExplains how to speed the optimal shape design process using a computer. Outlines the problems inherent in optimal shape design and discusses methods of their solution. Concentrates on finite element approximation and describes numerical realization of optimization techniques. Treats optimal design problems via the optimal control theory when the state systems are governed by variational inequalities. Provides useful background information, followed by numerous approaches to optimal shape design, all supported by illustrative examples. Appendices provide algorithms and numerous examples and their calculations are included. |

... forces . These forces cause deformation of the body so that the point x , x = ( x1 , x2 ) of the undeformed body becomes the point x ' , x ' = ( x1 , x2 ) of the deformed body and x ' can be written as x ' = x + u ( x ) , where u = ( u1 ...
