Experimental and analytical assessment of axial crushing of circular hybrid tubes under quasi-static load
TL;DR: In this paper, the axial crushing behavior of circular aluminum/glass-epoxy hybrid tubes is studied experimentally and analytically, and the experimental results reveal that stacking sequence has a considerable effect on crashworthiness characteristics, for example, the absorbed energy is more than three times of aluminum tube with the same aluminum wall thickness.

Mathematical Model for Axial Crushing of Hybrid Square Tubes
TL;DR: In this paper, a new theory was proposed based on collapse mode of metal square tubes and considering off-axis strength of each layer of composite, and an expression was derived for mean crushing load and folding wave length in terms of mechanical properties and geometrical dimensions of metal tube and composite prepregs wrapped around it.
