Elastodynamic contact problem for an interface crack under an oblique harmonic loading

The current study is devoted to solution of the two-dimensional elastodynamic problem for a cracked bimaterial loaded by harmonic wave. This investigation takes into account the reflection and refraction of oblique waves at an interface between two dissimilar solid half-spaces which contains a crack. The problem is solved by the method of boundary integral equations using an iterative algorithm. The dynamic stress intensity factors are given in the wide range of wave numbers for different properties of the bimaterial with the focus on the effect of the cracks' closure. (C) 2014 Elsevier Ltd.
