In the paper stress-strain behavior of solid around working in case of out-of-limit deformation when flat strain occurs is studied. Two limit variants are considered: when modulus of volumetric compression has much more value than modulus of decrease and vice a versa. In the first variant sizes of solid destruction zone are obtained, depending on limit strains of elasticity and strength of solid material. In the second variant solution at destruction zone differs from traditional elastic plastic solutions by maximal tangential stress increases with increasing of distance from working contour.
