โฆ Synopsis
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.

Weight functions are developed for determining stress intensity factors of cracks along an interface between two linear, elastic materials. As a result of the interface, both mode I and II components will be present for all but very special loading cases. The weight functions are employed to produce
## a b s t r a c t The problem of two equal-length collinear cracks in an infinite sheet is treated using the weight function method. Exact weight functions for the inner and outer crack tips are derived based on the crack opening displacement solution for a reference load case. These weight functi
