Bistable prestressed shell structures. (English) Zbl 1119.74473

Summary: 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.
