摘要：
Mixed-mode stress intensity factors were computed for kink cracks in front of a pre-existing semi-infinite crack. It will be shown that the differences between the weight function considerations by Cotterell and Rice and highly precise results from literature are a consequence of higher-order terms and mixed terms in the general weight function representation.
