Abstract: A degenerated nine-node-shell element and interpolation formulation for stress resultant vectors are used. Fifty-two selected experiments previously performed by the second author on the elastic buckling of clamped thin-walled ...

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: An elastic, nonlinear, Ritz analysis has been developed to allow investigation of the imperfect behavior of axially compressed orthotropic fiber reinforced polymer cylindrical shells. In a particular ...

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: Buckling of pressure loaded cylindrical panels is investigated using a fully nonlinear Ritz solution procedure and a classical bifurcation analysis of an idealized model. The dialectic between these two contrasting approaches ...

Abstract: In this paper, the effects of geometric imperfections on the nonlinear buckling behavior of rigidly jointed single-layer lattice domes under vertical loading have been studied. A commercially available finite-element code ...
