Crack initiation and fast crack propagation in the Single Edge Notch specimen are investigated within the two-dimensional linear elastic fracture mechanics confines. The influence of the initial crack length and the initial loading (bluntness) are pursued and the phenomenon of terminal velocity is studied. The analysis is performed using the SMF2D code which is based upon the simultaneous employment of both a stationary and a moving coordinate system, thus providing a continuous and smooth crack extension.
