Crack Waves 98
John W Morrissey
The scattered field generated by horizontally polarized incident shear waves in a system of layers having a flaw at the interface is studied. The physical model is idealized to the case of a crack sandwiched between two dissimilar media of infinite height. The local intensification of the dynamic stresses due to the crack is analyzed for incident waves directed at an arbitrary angle.
Results of numerical computations are obtained by solving pairs of coupled integral equations and reveal the variations of the stress and displacement fields with ratios of densities and shear moduli of the two adjoining materials. Previous article in issue. Next article in issue.
