Abstract
Conditions of brittle fracture arrest occurring in rolled sheet of low-alloyed steels at a specific temperature are considered. The problem of revealing correlation between this temperature, thickness of testing specimen and material properties is analyzed using finite element method for computer simulation of unstable crack propagation in 3D setting with specified local criteria of brittle and ductile fracture.
