The concept of averaging of stresses in the problems of the two-parameter fracture mechanics

Abstract

The article illustrates the application of the Neuber-Novozhilov concept for averaging of stress to before tip of a crack/cutout in solving of contemporary problems of two-parameter fracture mechanics, aimed at creation of models and criteria of body limit state and search of a crack path. As a parameters of tightness strain in the vicinity of the crack tip are used nonsingular components of T-stresses of the stress field.
