Abstract
Tubular systems are proposed to use as energy absorber because they are cheap and they are easy to manufacture; recently some researchers use elliptical tubes as energy absorbers. In this work, the influence of elliptical ratio on energy absorption capability and load carrying capacity and stresses of mild steel elliptical tubes has been investigated both experimentally and numerically. The experimental analysis was conducted by using a Zwick Type BT1-FB050TN testing machine. In addition to the experimental work, a computational analysis using ANSYS is made to predict the loading and response of such tubes where series of models were performed with elliptical ratios ranging from 0.5–1.5. Comparison of experimental and numerical force- and energy-displacement responses are presented.
