Маломасштабна пластична зона передруйнування в точці перетину ліній мікропластичного деформування

Abstract

The small-scale plastic prefracture zone at the point of intersection microplastic deformation lines in the determined. The problem on the plastic zone inserted to the symmetric problem of the theory of elasticity for a plane wish four straight tangential rupture lines emerging from it point. Two of them are semi-infinite, and two have a finite length. The exact solution of the problem is constructed by the Wiener-Hopf method.
