heal.abstract	The crumpling of thin-walled frusta, under axial compression, in the 'concertina' mode is studied. The energy expended in bending at the plastic hinges and in stretching the metal between the hinges is minimized for the total decrease in height due to collapse. The thinning of the cross-section due to stretching is neglected. A theoretical model has been developed and numerical results are obtained that show the effect of slenderness, t/D, and the semi-apical angle of the frusta. Good qualitative agreement in trends is exhibited when comparison with available experimental results is made. © 1986.	en
