摘要：

The behaviour of composite elliptical thin walled cones subjected to quasi-static axial crushing is examined experimentally. Series of experiments were performed for composite elliptical cones with the same ellipticity ratio and different vertex angles ranging from 0degrees to 24degrees. Experiments showed that the catastrophic failure mode is avoided by deviating from the elliptical tubular shape to the elliptical conical one. A significant enhancement in load carrying capacity and energy absorption capability was seen in the case of elliptical conical shells. (C) 2004 Elsevier Ltd. All rights reserved.
