✦ Synopsis

The paper is concerned with the shape optimal design of a large displacement contact problem. Contact wilth the prescribed friction is assumed. The optimal design problem consists of finding the domain boundary in the contact zone to minimize the contact stress. The mixed finite element method is used to discretize this optimization problem. The necessary optimahty condition is formulated. The augmented Lagrangian approach is used to solve numerically the state system. The conjugate gradient method with projection is used as an optimization method. Numerical examples are provided. 0 1997 Civil-Comp Ltd and Elsevier Science Ltd.

In this paper, we present an a posteriori error analysis for mixed finite element approximation of convex optimal control problems. We derive a posteriori error estimates for the coupled state and control approximations under some assumptions which hold in many applications. Such estimates can be us
