Abstract: Asymptotic and fully nonlinear analyses are used to find the maximum load carrying capacity of ring-stiffened cylinders subjected to hydrostatic pressure. Both procedures use ring elements with harmonic description of ...

Abstract: The interaction of local and overall buckling has been analyzed using a novel finite element in which local buckling deformation has been embedded. Amplitude modulation, a key feature of the interactive buckling, has been ...

Abstract: Buckling behavior of axially compressed sandwich columns exhibits a variety of interesting phenomena. The column can buckle in a long wave “overall mode” or a short-wave “wrinkling mode,” the latter involving severe bending ...

Abstract: The imperfection sensitivity of ring-stiffened anisotropic composite cylindrical shells under hydrostatic pressure is investigated using an asymptotic procedure. To this end, a finite-element formulation based on ...

Abstract: The interaction of local and overall buckling in thin‐walled columns is considered. A finite strip method in conjunction with the theory of mode interaction is developed to study the problem. The method is applicable to ...

Abstract: Features of the phenomenon of interactive buckling of thin‐walled columns are briefly reviewed. The theoretical results are compared with the recent test results from University of Sydney and earlier results from Cornell ...

Abstract: A delaminated composite ring under external pressure is studied to understand the effect of curvature on delamination buckling and growth. Examples with differing crack lengths and delamination locations were considered. ...

Abstract: A new analytical model has been developed for a study of the response of thin‐walled beam‐columns having doubly symmetric cross sections. The novel features of the model are that: (1) It incorporates the interaction of ...

Abstract: A buckling analysis of anisotropic composite layered plates is presented. The analysis employs finite strips in conjunction with a perturbation technique and is applicable to rectangular plates with one pair of opposite ...
