The influence of harmonic wave on the concentration of stresses in the infinite solid with pliable disk-shaped inclusions

Abstract

The propagation of harmonic elastic waves in infinite solid with the system of disc-shaped inclusions
of low rigidity is investigated. The problem in the frequency domain is reduced to the system
of boundary integral equations by the functions of displacement jumps on the inclusion. Using
numerical method, the analysis of the distribution of dynamic stress intensity factors of separation
in the vicinity of the inclusions depending on the wave number of inclusions at various distances
between defects and the various ratio between the elasticity moduli of the matrix environment and
disc-shaped inclusion is carried out.
