A front bumper of a car is attached to the main vehicle structure by using hollow metals. This paper investigates various cross section profiles that can be used as bumper attachments. Several cross section profiles with the same circumscribe are firstly selected, i.e. round, square, triangular and hexagonal shape cross sections. Each model is then numerically impacted in an axial mode as if it is crashed into a rigid wall with an impacting velocity of 10 m/s or equivalent to 36 m/s. A dynamic-explicit open source software Impact is employed to do the simulation. The displacement results are monitored in the first 1:8ms then compared to the models that can absorb better showing the less displaced in certain examination nodes. The results shows that the triangle cross section performs better compared to other cross sections.
