Anonlinear thin-walled elastic orthotropic body with a mode 1 crack and a fracture process zone near its tip is considered. An equilibrium boundary-value problem is stated in terms of the components of the displacement vector. The equations relating the components of the stress vectors at points on the opposite boundaries of the fracture process zone with the components of the vector of displacement of these points relative to each other are used. The mechanism of development of the area of passive deformation around the fracture process zone is established using the solution of the boundary-value problem. The strain state at some points of the area of passive deformation is analyzed. The evolution of the area of passive deformation under loading of the body is studied. The area of passive deformation is compared with the nonlinear zone near the crack tip.
