The contact stress distribution is frequently not regular. It may contain singularities reducing the lifetime of machine elements. In order to eliminate such stress singularities, the application of contact pressure control is recommended in the contact conditions. In the paper, several classes of optimization problems are formulated for stationary and sliding contacts. Further, they are illustrated by specific examples. The relation to wear process is made as a natural way to attain the steady state contact profile satisfying the optimality conditions corresponding to minimization of the wear dissipation rate. It is assumed that the displacements and strains are small and the materials of the contacting bodies are elastic.

In this paper, the problem of optimizing the contact force distribution between a rigid obstacle and an elastic discrete body is considered. The initial distances between the bodies are taken as design variables and the equilibrium total potential energy as the cost function.A standard result is now that if an isoperimetric design constraint prescribing the "gap volume" is included, the resulting distribution of contact forces is constant; a desirable property. This article includes an investigation of the outcome when the design constraint is interchanged with general behavioural constraints on the contact forces.
