It is developed the method of the stress state analysis in the problems of flat plastic deformation for areas with variable contact forces of friction, based on a layer-by-layer division of deformation contours of tangential stresses. With the use of a parabolic approximation of the conditions of plasticity are found solutions of the equilibrium equations of a plane problem for each layer. In relation to the process of precipitation rectangular strip analysis of stress distribution is made on the contact surface and on the height of the deformation zone.
