SPATIAL PROBLEM OF INTERACTION OF LONGITUDINAL WAVES OF A CYLINDRICAL CAVITY IN AN ELASTIC MEDIUM

Among practical problems, one of the most topical are problems in which the propagation of wave processes in three-dimensional elastic bodies is considered. Such processes are of great importance in the construction of underground cylindrical structures. They occur during earthquakes and in a number of other cases. The main elements of most structures are cylindrical cavities. Therefore, the study of dynamic processes in such objects is of the greatest interest. This article discusses the development of a numerical algorithm for studying wave processes in three-dimensional elastic cylindrical cavities under the influence of stationary loads.
