In this paper the earlier elaborated finite-element method of calculating the stress intensity factor for stationary cracks at dynamic loading by means of cohesion finite elements and on the basis of the method of lines is generalized for high-velocity cracks. The method in question does not require rearranging the finite-element mesh. The crack growth is modeled by consecutively releasing the nodes located on the crack line. The calculated data are compared with the analytical solutions of other researchers and with the experimental data.
