Abstract

The specific features of various approximate analytical methods for estimating the state of stress in the zone of stress concentration of stresses and strains, including the Neuber, Hardrath–Ohman, and Molski–Glinka methods, are compared. A method for the modification of the methods to extend the range of the strains under study up to fracture is proposed.

Keywords:
