Cracks in flat plates are often found to be about 45° to the plate plane for some metals and alloys. There are two identical 45° directions to the plate plane and the choice of crack direction seems to be random. Experiments have shown that, for large flat panels, the long ductile crack propagation exhibits a regular alternating pattern, i.e. the crack switches to the other direction after propagates some distance regularly. In this paper, a numerical examination of the details of the formation of the alternating crack pattern is presented. Relevant material parameters and their influencing factors to the alternating behavior of cracks are discussed.
