Propagation of spherical shock waves in a contiguous elastic-plastic environment

Abstract

This article studies the propagation of one-dimensional spherical shock waves in a homogeneous
medium, represented by soil or ground, modeled as a continuous elastic-plastic medium. The research
assumes that the loading shock waves in the elastic-plastic medium filling the surrounding space
propagate at a constant velocity. Furthermore, the effective use of directional blasting technology in
construction, mining-geological industries, and other technical fields requires determining the relevant
mechanical parameters of continuous elastic-plastic media subjected to shock loads. Within the theory of
small elastic-plastic deformations, the relationship between the components of the stress and strain
tensors in a spherical coordinate system is taken into account.
