Micro Abstract:
Kalker variational principle allows to solve consistently unilateral contact problems in terms of the normal traction as the prime unknown variable. It is particularly useful for the development of boundary elements for Boussinesq problem in half-space approximation. This principle is extended to account for adhesion between solids. The contact pressure may take negative values governed by an adhesive work potential and surface separation energy. The latter is evaluated via level-set.
