Non-fracture prediction of a C–Mn weld joint in the brittle-to-ductile fracture transition temperature range: Part I: Experimental results and numerical study

This paper evaluates the brittle fracture risk for a C–Mn weld in the upper shelf of the brittle-to-ductile transition: the criterion considered is based on a critical stress σth, with the failure probability related to the volume around the crack where the maximum principal stress exceeds σth.
