A Simple Analysis of the Swage Autofrettage Process

Abstract

Many solutions have been reported for the hydraulic autofrettage process. In this report a simple analysis of the swage autofrettage process is presented. The contact pressure at different locations is determined as a function of interference. The deformation and stress distribution during autofrettage is obtained. At the end of the autofrettage process, the permanent bore enlargement and residual stresses are calculated. Numerical results are presented in graphical form. Keywords: Gun tube, Autofrettage, Residual stress, Hardening, Swaging, Plasticity, Bauschinger effect.
