Original Abstract

Most fracture mechanical models do not take the materials microstructure into account and use averaged material properties although the real crack flanks and fronts exhibit microstructurally induced tortuous shapes. These influences the stress-strain field at the crack front as well as the related stress intensity factors. This phenomenon was investigated by some authors only for remote mode I loading and was named geometrically induced shielding. This study is focused on the analysis of the stress intensity factors for rough cracks loaded in the shear mode II by modelling the Compact-Tension-Shear specimen containing cracks of various roughness.
