| Abstract: | A new algorithm for solving dynamic contact problems involving deformable bodies is proposed. The algorithm is based on formulation
of the boundary conditions for the contact interaction with allowance for Coulomb friction in the form of quasivariational
inequalities. The algorithm is numerically stable and satisfies geometric constraints in the a priori unknown contact region
and conditions specifying that the normal pressure be nonnegative and that the vectors describing tangential velocity and
shear stress during slip be oppositely directed. Results are presented from calculations performed for a contact problem for
an elastoplastic body in a two-dimensional formulation.
