An inextensional collapse mechanism is proposed for the crumpling of thin-walled double top-hat sections when subjected to axial load. A 'symmetrical' type of failure consisting of stationary circumferential hinges and travelling inclined hinge lines is studied and it was verified through the test series of specimens of a polymeric plastic material. Predicted loads based on the collapse modes encountered are compared with experimentally obtained ones and found to be in good agreement.
