The crashworthy ability of glass/epoxy (GFRP) square tubes with induced holes was studied under quasi‐static axial crashing. Four design parameters were chosen, each at three levels, to calculate crashworthiness indicators. The design variables are hole diameter (d), hole position/specimen length (P...
