Response of pultruded composite tubes subjected to dynamic and impulsive axial loading
Journal Contribution - Journal Article
The energy absorption of circular pultruded composite tubes subjected to axial crush load, transmitted by
a small attached mass accelerated by means of an explosive load is presented in this paper. Different
masses of explosive are used to provide a range of transmitted impulse and crushed distance of the pultruded composite tubes. The in?uence of the mass of the explosive on the tube response is investigated
with regard to crushed distance, the average crushing force and the speci?c energy absorption (SEA). The
crushing distance increases with increasing transmitted impulse. The results and failure mode are also
compared with compression tests carried out on a servo-hydraulic machine (type: MTS-309).
