Abstract
The paper is concerned with the shape optimal design
of large displacement contact problem. The contact
with the prescribed friction is assumed. The optimal design
problem consists in 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 optimality 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.
