heal.abstract	Theoretical and experimental investigations into the quasi-static plastic collapse of thin-walled PVC tubes containing a number of geometrical discontinuities in the form of internal axial grooves of constant depth, with the aim of providing information about its behavior as an energy-absorbing device, are reported. An inextensional collapse mechanism for folding the shell in a non-symmetrical diamond fold mode, taking into account stationary, circumferential inclined and traveling plastic hinges, is considered. The failure modes and the mean postbuckling load necessary to perform the operation are discussed. Practical results based on the collapse modes encountered, when compared with those obtained experimentally were found to be in good agreement.	en
