Abstract

An exact elastic-plastic solution for the stresses in a flat ring subject to pressure is obtained on the basis of J₂ deformation theory together with a modified Ramberg-Osgood law. The results are assessed on the basis of Budiansky's criterion for the acceptability of J₂ deformation theory. By using exact elastic-plastic stresses, the radial enlargement and the permanent increase in thickness of the ring at the hole are obtained. Upon release of the pressure, residual stresses around the hole are produced.
