Odbicie płaskich fal naprężenia w ośrodku sprężysto-plastycznym o zmiennej granicy plastyczności

The problem of propagation of plane stress waves in a layered medium consisting of an elastic-plastic layer and elastic semi-space is considered. At outer surface of the layer, the suddenly increasing pressure (which then monotonically decreases to zero) is given. It is assumed that the layer is inhomogeneous with respect to the yield limit. The results obtained in the present paper can be applied to estimate the dynamic forces acting on a structure placed on soil.
