Abstract
The postbuckling behavior and failure of composite cylinders subjected to external hydrostatic pressure are investigated by a finite element method and test. A nonlinear finite element program, ACOS, is used for the postbuckling progressive failure analysis of composite cylinders. A total of 5 carbon/epoxy composite cylinders were fabricated and tested to verify the finite element results. For comparison, analyses by MSC/NASTRAN and MSC/MARC are additionally conducted. Among the softwares, the finite element program, ACOS, predicts the buckling loads the best with about 11 to 26% deviation from experimental results except for one specimen. While the finite element analysis shows global buckling modes with 4 waves in hoop direction, in the experiments the local buckling appears first and results in the final failure without global buckling.
