Modern methods of analysis of contact problems are based on the variational approach which together with the finite element method expand possibilities of analysis in many cases. In this contribution, generalizations of classical variational formulations are given in the case of contact of rubbing and wearing solids. Variational formulations are developed starting from strong forms of governing relations for two contacting solids and an interfacial layer of wear debris. A definition of a contact gap between contacting solids is extended taking into account wear profiles. Constitutive models of friction, wear and frictional heat with anisotropy and inhomogeneity effects are applied. Using the finite element method, discretized forms of the variational functionals are presented.
