heal.abstract	A procedure based on either of the fracture criteria, i.e. the two-term S2-criterion (S2) and the T-criterion (T), is proposed to simulate crack initiation and propagation from an initially inclined crack. According to this model the running crack, during its initial stage, follows a strongly zig-zag trajectory, forming successive kinks. Then, after a certain number of steps, the crack path is stabilized in a straight line, until complete fracture of the plate occurs. The directions of the successive kinks are essentially the same as those given by the two-term S2- criterion for brittle materials and the T-criterion for ductile materials. © 1985.	en
