On the feasibility of shear stress estimation at interfaces of block-structured medium

Abstract

In the work, we study the stress state at interfaces of block-structured medium and its effect on the deformation response of the materials to dynamic loading by the movable cellular automaton method. The simulation results suggest several deformation response parameters qualitatively dependent on the character of the stress state. These parameters are the relative tangential shear displacements initiated under dynamic loading and certain characteristics of the frequency spectrum of their velocity in block-structured medium. The performed analysis allows us to put forward a complex approach to the stress state diagnostics of fragments of active interfaces in various block-structured medium, particularly in hierarchical geomedia.
