Structural Viability of Steel with Stress Concentrations under Uniaxial Tension

Abstract

Abstract—Two types of mechanical characteristics of structural steel in uniform and nonuniform force fields are presented. In the science of metals and alloys, assignment by type is a fundamental concept. An analytical apparatus is developed for finding relations between the fracture resistance and basic mechanical characteristics of the metal, so as to assess the structural viability of steel in nonuniform force fields with annular stress concentrators, under uniaxial tension. The structural viability of steel with regular stress concentrators is assessed, and their low-temperature embrittlement is estimated.
