Modeling the formation of residual stresses in thin-walled cylindrical samples after plastic surface hardening of inner and outer surfaces.

The results of experimental research on residual stresses and plastic deformations by the hardening of the outer and inner surfaces of thin-walled Kh18N10T steel tubes by means of microbeads are described. A phenomenological model for calculating residual stresses and deformation by two-way tube hardening is proposed. A method for parameterization of the mathematical model is presented. The adequacy of the model was verified, and the calculated and experimental data were matched. [ABSTRACT FROM AUTHOR]
