Investigations have been carried out to determine the deformation modes and load-compression characteristics of tapered, thin-walled truncated frusta and tubes of square cross-section of rigid polyvinychloride (PVC). The latter were fabricated from sheet material and bent and seam welded; they constitute potential absorbers of energy. A theoretical model for predicting the mean loads in the plastic post-buckling range is developed on the basis of an inextensional folding mechanism and the notion of stationary and travelling plastic hinges. The analytical results are compared with experimental ones and show good agreement. © 1989. (EN)
