Summary
At the tip of interface cracks in bimaterials, residual stresses provide strong mode II contributions while four-point-bending loading leads to dominant mode I components of applied stress intensity factors (ASIF). Thermal stress intensity factors (TSIFs) primarily depend on crack length ratio a/w and Dundurs’ first parameter α. ASIFs due to bending are mainly dependent on crack length whereas Dundurs’ second parameter β plays a minor role in both, thermal and mechanical loading cases. In this paper, effective SIFs for combined loading situations are derived and discussed.
