Abstract

Copyright ©: SDSS'2016. The stability of thin circular shells under proportional and non-proportional loading, i.e. axial tensile stress and external pressure is extensively investigated. Two plasticity theories are considered; the flow and the deformation theory of plasticity. The results obtained confirm that under over-constrained kinematic assumptions the deformation theory tends to provides lower values of buckling pressure and the discrepancies in the results from the two plasticity theories increase with increasing thickness ratios, tensile stresses, boundary clamping E/σy and ratio.
