Abstract

We propose a method aimed at the evaluation of the amplitude of singularity and dimensionless angular distributions of the second terms in the expansions of stresses, strains, and displacements in the plastic zone in the vicinity of the crack tip. The method is based on the combination the Hutchinson-Rice-Rosengren-type analytic solution and a numerical solution obtained by using a modified method of boundary layer. The presented results enable us to analyze the effects of constraints in broad ranges of conditions of biaxial loading.
