摘要：

As a rule, brittle fracture is associated with the presence of a Griffiths crack. In this case, the cause of instantaneous fracture is the crack growth. The accumulation of pores and the embrittlement of the initially ductile metals under the action of a long-term temperature effect also causes unpredictable brittle fracture. An attempt to analyze and predict such fracture is made in the present work.
