Abstract: A procedure, developed for predicting the elastic-plastic general axisymmetric collapse of stiffened and unstiffened cylinders, is presented. This permits the formulation of reliable lower bounds ...

Abstract: An elastic nonlinear Ritz analysis is used to investigate the behavior of axially loaded imperfect cylindrical shells. It is shown how the initially positive contributions arising from the shells ...

Abstract: Nonlinear Ritz analysis is used to investigate the elastic buckling behavior of pressure loaded cylinders. Careful analysis of the energy changes during the buckling process allows definition of ...

Abstract: Conventional design procedures for rigid jointed frames encourage a situation in which more than one buckling mode could occur simultaneously. Even though this practice is known to often give rise to increased sensitivity ...

Abstract: Elastic buckling of pressure‐loaded spherical space domes is reinterpreted using a recently postulated reduced‐stiffness model. By means of extensive nonlinear numerical studies into the effects of geometric imperfections, ...

Abstract: A rigid, perfectly plastic mechanism analysis, embodying interactive uniaxial membrane and bending plasticity, is used to predict the form of localized impact damage for tubulars. An extension ...

Abstract: Offshore structural circular tubular members suffering from local dent damage can develop extreme stresses at locations around the dent area. An analytical method for the prediction of elastic ...
