A statistical approach is presented to strength analysis of metals under conditions of low-temperature embrittlement. The approach involves two categories of defects leading to fracture: primary defects, present in the original structure in the form of microvoids, microcracks, inclusions etc., and
Based on the combined micro-and macro fracture mechanics, the two requisites necessary for the crack propagation, that is, the energy unstable requisite and the critical local stress requisite, are derived for the low-stress brittle fracture of notched specimens. Thus the fracture criterion was obta
