Computer modelling and numerical analysis of dynamic burnishing (shoot peening) process in object surface layer internal stresses pattern aspect were the aims of the work. The influence of chosen process parameters on state of stresses was determinate. Incremental Lagrange formalism and adequate measures of stresses and strains were used in the paper. The application in ANSYS program, which allows to determinate the stains of stresses and strains in any point of surface layer of object and any time during the process, was created. The surface layer material was treated as an elastic/viscous-plastic body with nonlinear mixed hardening. Although the shoot was considered as ideally rigid or elastic body. Simulations were carried out basis on three levels experiment design. Simulations results were approximated by regression equations in square polynomial form. Compromising solutions sets for substitute optimization criterion were defined.
