Boundary Integral Equations in the Frequency Domain for Interface Cracks under Impact Loading

In the study interface cracks between two dissimilar homogeneous isotropic half-spaces undergoing impact loading are considered. The problem is solved using the boundary integral equations in the frequency domain. The distributions of the displacements and tractions at the bonding interface and surfaces of the cracks are obtained and analyzed. The stress intensity factors (opening and shear modes) are computed for different load conditions and various properties of the bimaterial. The results are compared with the ones obtained in the time domain. (© 2012 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim)
