Impact response of tubular structure with internally stacked circular tubes / Naziratie Assrinie Assan

Extensive study had been carried out to determine the impact response of various tubular structures. In the event of collision, vehicles are subjected to very high Initial Peak Force (IPF) due to a large change in momentum in a very short period of time. This can lead to severe human injuries and da...
