摘要：

In this paper experimental study of plastic deformation of aluminum frusta when reinverted is presented. Effects of changing the angle of frustum as well as frustum wall thickness on the absorbed energy are investigated. The details of the experimental plastic inversion and reinversion are given. Obtained results show that it is possible to use the inverted aluminum frusta several times, thus they are reusable collapsible absorbers. (C) 2002 Elsevier Science Ltd. All rights reserved.
