heal.abstract	In the present paper, we deal with the crush behaviour of axisymmetric composite structures consisting of circular tubes and frusta made from a chopped-strand glass mat and polyester resin and subjected to dynamic axial compression exerted by a drop-hammer. The effect of specimen geometry and loading rate on the energy-absorbing efficiency is studied in detail. Attention is also directed towards the mechanics of the axial crumpling process from the macroscopic point of view, and the systematic study of the microfailure process and understanding of the crack propagation mechanism during the stable collapse of the shell. This gives a somewhat more complete aspect on the actual fracture mechanics during the failure of the composite material tested. Finally, the dynamically obtained experimental results are compared with the static ones for shells of similar geometry, and useful semi-empirical relations concerning the amount of energy absorbed and the post-crushing loading are derived for the material tested. © 1994.	en
