Fracture characteristics of advanced high strength steels during hole expansion test
This study was performed to estimate the stretch-flangeability of two important advanced high strength steel (AHSS) sheets, i.e. DP980 and TRIP1180, using hole-expansion test (HET). Moreover, the effect of hol...

Fracture of a thin power-law nonlinear material with a crack using the DCB model
A thin power-law nonlinear material with a crack is studied. For a thin cracked structure, we simulate the layer with an edge crack or a center crack as a double-cantilever beam (DCB) or a double-clamped beam,...
