摘要：

The paper investigates a cylindrical shell which has two stable configurations, due to a particular distribution of residual stresses induced by plastic bending. The basic mechanics of the bistability are explained, along with details of the plastic forming. A comprehensive analytical model is developed which predicts the residual stress distribution and bistable configurations of the shell. Good correlation has been found between experimental results and predictions from this model. (C) 2004 Published by Elsevier Ltd.
