Abstract:
In this paper, we consider a nonstationary mixed problem of impact of a rigid plate on the face surface
of the base body containing inside itself a central foreign inclusion. Formulated in terms of stresses and
velocities of displacements, the mixed problem is modeled numerically by means of an explicit difference
scheme of a through count, based on the method of the spatial characteristics. The results of a change in
the wave fields in a doubly connected domain are presented in the form of graphs. The analysis of numerical
information made it possible to investigate the dynamic effects of stress concentration in the neighborhood
of the contact of a doubly-connected domain, as well as near the corner points of a foreign inclusion.
