On Strain-Hardened Circular Cylindrical Shells

Abstract

A consistent kinematic hardening theory termed complete hardening, based on a Tresca initial yield condition, has been applied to determine the general flow laws for rotationally symmetric shells. Representative “long” and “short” cylindrical shell problems with zero axial load are solved using complete hardening and a simpler but approximate kinematic hardening theory, termed direct hardening. The direct-hardening results compare favorably with the complete hardening ones.
