The article considers the numerical solutions of some spatial non-stationary problems for elastic and elastic-plastic bodies of finite dimensions in the form of a parallelepiped, and for them the regularities of the 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. Based on the method, an algorithm for calculating the relationship between stress and seismic environment was developed, which made it possible to generate a code and design an information system for calculating the wave process
