## Abstract An optimal preconditioning procedure for the numerical solution of two‐dimensional Dirichlet problem for Lamé equations by boundary element method is constructed. An efficient algorithm for the above problem is also developed.
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 us
