Rigid inclusion in problem for a viscoelastic body with crack
This paper investigates the problem of equilibrium of three-dimensional viscoelastic body with a rigid inclusion. The cases without delamination and partially delaminated inclusion are considered. The corresponding formulations of problems in the form of the boundary value problem, and also in the variational form are studied, we prove the equivalence of these formulations. Existence and uniqueness of solutions of the problems are proved.
