Abstract
The article considers an approach to increasing the stress state in the elastic-plastic deformation zone during surface plastic deformation. The technical idea of solving the problem is based on the complication of the kinematics of a two-radius roller. To achieve this goal, the finite element method based on the ANSYS computer program was used, which makes it possible to determine the values of temporary, residual stresses and strains for different schemes of reversible surface plastic deformation with a two-radius roller. It has been established that the greatest influence on the stress-strain state in the deformation zone is exerted by the scheme of reverse rotation of a two-radius roller located at an angle of 45 degrees relative to the direction of movement, and the least effect is when hardening with a two-radius roller, the axis of rotation of which coincides with the direction of movement.
