Experimental and numerical analysis on the geometrical parameters towards the maximum SEA of CFRP components

The numerical prediction followed with experimental validation, confirming that the energy absorption capacity of carbon composite tubes increased to a maximum t/D ratio at 0.092, before experiencing a reduction. It has also been found that the geometry of the triggering mechanisms contributed to a change in the initial peak and mean crush loads of composite tubes. In this paper, the effect of the triggering mechanisms on the energy absorption characteristics of composite tubes for crashworthy applications are successfully demonstrated.
