Abstract

A methodology is developed for assessing the deformational stability (fracture resistance) and carrying capacity of a steel product or structural component operating in the presence of stress concentrators with different types of loading, near room temperature. A relation is found between the fracture resistance of structural steels in uniform and nonuniform force fields, in terms of parameters reflecting the state of the metal in elastoplastic loading. Dynamic loading is found to increase the critical level corresponding to transition to the brittle state for high-strength steels of the first kind. By contrast, no critical level exists for steels of the second kind, characterized by greater plasticity and carrying capacity. By the proposed methodology, alloy structure ensuring sufficient reliability of the product or structural component may be maintained.
