Abstract By using the dislocation model for a moving internal crack subjected to the dynamic antiplane stress, the elastodynamic mode III stress intensity factors at the crack tips have been derived. Based on the dislocation concept applied to a stationary crack subjected to dynamic SH loadings, we represent a moving internal crack subjected to SH (horizontal polarized shear waves) with an array of continuous distribution of screw dislocations, all parallel to z axis. The densities of the dislocations as well as the phase lags are expressed as a system of singular integral equations, which contains Bessel functions. The effects of the wave number, the input incident angle and Mach number on the stress intensity factors are presented.
