Margolin, V. Shvetsova] The authors proposed a criterion for the initiation of brittle fracture which takes into account the role of normal and effective stresses during microcrack initiation. A calculation and experimental method of determining the parameters included in the condition of initiation of brittle fracture is developed. The method is used to select these parameters for 15Kh2MFA steel'in the initial and deformed condition. The dependence of the critical stress of brittle fracture on plastic strain for different loading histories is analyzed. The use of the proposed criterion of brittle fracture makes it possible to predict satisfactorily the temperature dependence of the cracking resistance parameter KIc(T) and effect of prior strain on this parameter. The modified formulation of the criterion of brittle fracture makes it possible to describe the fracture process for different stress-strain states of the materials.
