Abstract
The study is devoted to the application of boundary integral equations to problems for interface cracks with initial opening under harmonic loading. As a numerical example the initially opened linear interface crack under the normally incident tension–compression wave is considered. The problem is solved taking the contact interaction of the crack’s faces into account. The convergence of the iterative algorithm is analysed and the stress intensity factors (opening and transverse shear modes) are given for the wide range of the wave number.
