Crevice fracture stress
The split fracture stress σ f * is a critical tensile stress at which a split fracture can occur locally. In the diagram, there can be no more brittle fracture from the point of intersection of the crevice fracture stress with the yield point R e . The point of intersection is given as the transition temperature T ü . From this point onwards, plastic deformation of the material sets in and a split fracture occurs. The crevice fracture stress thus represents a relationship between stress and temperature.
