A small-scale plastic zone at the point of intersection of microplastic deformation lines is identified. The problem on the plastic zone is reduced to a symmetric elasticity problem for a plane with four tangential displacement discontinuity lines emerging from this point. Two of them are semi-finite, while the other two are of finite length. The exact solution of the problem is found using the Wiener–Hopf method.
