摘要

The classic problem of a circular tube or ring buckled by external pressure is investigated by including geometric nonlinearity, material nonlinearity and initial residual stress. Perturbation theory for buckling and immediate postbuckling agree well with numerical integration. It is found that for softening materials the postbuckling may be unstable and catastrophic snap through may occur. (C) 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
