The article considers numerical solutions of some spatial non-stationary problems for elastic and elastoplastic bodies of finite dimensions in the form of a parallelepiped, and for them the laws of propagation of three-dimensional waves are studied. An explicit difference scheme based on a combination of the methods of bicharacteristics and splitting in spatial variables is presented. Based on the described method, the elastic problem of longitudinal and transverse impact on a parallelepiped with one rigidly fixed end is solved. The features of the propagation of three-dimensional waves and the influence of a change in the speed of an external load on the pattern of wave propagation are studied, and some features of the propagation of dynamic stresses in the vicinity of a rigidly fixed end are revealed. The software was developed and tested for the robustness of the numerical calculation. Results, achievements of calculations in the form of isolines of normal stresses, performed for different points in time.
