Popis: | So far, we have studied growth of a crack only for the case when the load is applied normal to the crack and such that the crack propagates in a self-similar manner. However, often the loads are not aligned to the orientation of the crack. In such cases, the crack-tip stress field is no longer governed by a single opening-mode stress intensity factor K I but by a combination of the three stress intensity factors K I, K II, and K III. Moreover, the direction of crack initiation is not known a priori but depends on a failure criterion involving some combination of K I, K II, and K III. As a rule the crack follows a curved path. |
