We consider an equilibrium problem for an elastic body with a crack, on the faces of which unilateral non-penetration conditions and Coulomb friction are realized. This problem can be formulated as quasi-variational inequality. To solve it, the succe

An equilibrium problem for an elastic body containing a rigid inclusion is solved. There is a delamination crack on a portion of the interface between the inclusion and the elastic body. Mutual nonpenetration conditions are set on the crack faces. Ac

An equilibrium problem for a 3D elastic body with a crack is considered. We assume that nonpenetration boundary conditions and Coulomb friction law are imposed on the crack faces. This leads to the formulation of a problem as a quasi-variational ineq

A dual scheme for solving a crack problem in terms of displacements is considered. The dual solution method is based on a modified Lagrange functional. The convergence of the method is investigated under a natural assumption of H1-regularity of the s

We solve the semicoercive quasi-variational Signorini inequality that corresponds to the contact problem with friction known in the elasticity theory by a method of successive approximations. For solving auxiliary problems with a given friction occur

We consider an equilibrium problem for a 3D elastic body with a crack. Inequality-type boundary conditions are considered at the crack faces to prevent mutual penetration between them. This leads to the formulation of a problem with an unknown contac
