Abstract

Based on Tresca's yield criterion and the flow rule associated with it, the distribution of stress, strain and displacement in a linearly strain hardening elastic-plastic hollow shaft subject to a positive radial temperature gradient and monotonously increasing angular speed is investigated. Presupposing circular symmetry and plane strain conditions, the problem is accessible to an analytical treatment. It is found that - depending on the temperature difference between the outer and the inner surface - qualitatively different types of solutions may occur, and that such a temperature difference on the one hand reduces the elastic limit angular speed but on the other hand may increase the fully plastic angular speed slightly. The residual stresses after stand-still and subsequent cooling are depicted, too.
