Crack problems for solids with possible contact between crack faces

Abstract: In the talk, nonlinear boundary problems describing cracks in solids are considered. It is well known that the classical approach to the crack problem is characterized by the equality type boundary conditions corresponding to the stress-free surfaces. Peculiarity of the problems considered in the talk is that we impose nonlinear boundary conditions at crack faces. These conditions provide a mutual nonpenetration between the crack faces. From a general point of view the models analysed have an analogy with contact problems with unknown contact domains. New results of the theory are assumed to be presented in the talk.
