Abstract
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 0° to 24°. 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.
