Solution of the elastodynamic contact problem for a cracked body using the boundary integral equation method

摘要

This paper considers the mathematical formulation of the elastodynamic contact problem for a cracked body. The contact interaction of the crack edges in 2D is studied for the case of normal incidence of a harmonic tension-compression P-wave and shear-dilatational HS-wave, respectively. The problem is solved by the method of boundary integral equations along with a special iterative algorithm. The dependence of the stress intensity factor on the wave number is studied
