Abstract

The paper presents an experimental and two finite element theoretical investigations into the buckling of thick-walled circular conical shells under uniform external pressure. All three vessels failed by plastic lobar buckling. One of the theoretical analyses was based on plastic lobar buckling and one on plastic axisymmetric buckling. Both theories gave good results and this factor, together with the experimental observations, appeared to indicate that there is a link between plastic lobar buckling and plastic axisymmetric failure for these vessels.
