Abstract

The aim of the present paper is to investigate the influence of autofrettage on stress distribution and load bearing capacity of a thick spherical shell. Appling the maximum shear stress Theory and distortion energy theory an analytical equation for optimum radius c of elastic-plasic juncture, c(opt) is deduced in autofrettage technology. It revealed that the autofrettage increases the pressure inside the wall of a thing spherical shell that it can contain.
