A boundary-value problem in terms of the displacement vector components for the equilibrium state of a non linear elastic orthotropic body with a crack of normal separation is stated with regard for its prefracture zone. As a result of the numerical solution of the problem, the evolution of this zone under the loading is shown. The deformation field near the crack tip is studied.
