摘要：

A detailed discrete dislocation analysis is made of the behavior of tensile cracks. This discrete dislocation method minimizes the total energy of the configuration with respect to both the Burgers vector as well as the position of each dislocation. This approach is shown to be somewhat more accurate than those employed earlier. In particular, the present method is compared with the earlier discrete calculations as well as those which employ a single dislocation representation of the plastic zone.
