Abstract: In this article we report on the axial compression and crash behaviour of conical frusta, made from chopped strand glass mat and polyester resin. The effect of specimen geometry. i.e. thickness, length of the shell and its apical angle, on the energy-absorbing capability are being studied both experimentally and analytically. Attention is directed towards the mechanics of the axial crumpling process from a macroscopic point of view for facilitating engineering design calculations of the amount of energy dissipated and the buckling loads exerted during quasi-static loading.
