Plane Waves Due to Combined Compressive and Shear Stresses in a Half-Space

摘要

The plane wave propagation in a half-space due to a uniformly distributed step load of pressure and shear on the surface was first studied by Bleich and Nelson. The material in the half-space was assumed to be elastic-ideally plastic. In this paper, we study the same problem for a general elastic-plastic material. The half-space can be initially prestressed. The results can be extended to the case in which the loads on the surface are not necessarily step loads, but with a restricted relation between the pressure and the shear stresses. (Author)
