【Abstract】 The problem of a crack moving at a constant velocity interacting with SH wave in an anisotropic medium has been studied by the use of Fourier transform and Wiener-Hopf method. The integral representation of the displacement field and the closed form of the dynamic stress intensity factor at the moving crack tip have been obtained.更多还原
