A hybridized displacement discontinuity method for mixed mode I–II–III loading

A new hybridized displacement discontinuity numerical method is presented. The existing code FROCK is modified to incorporate loading mode III, and thus have a fully coupled solution for mixed mode I–II–III loading. The new code can be applied to homogeneous elastic bodies with small scale yielding and to cracks where one of the dimensions is much larger than the other two. The code combines both displacement discontinuity (DD) and stress...
