In this paper, the authors present the collapse modes classificationof tubes under axial loads.This topic is sensitivebecausepollution requirements are becoming more stringent and the emissions value ofCO2should be reduced. Therefore, to achieve this, modern vehiclesmust have a lower weight.The condition that a vehicle has a lower weight and high performance is that materials should have a lower weight and at the same timeahigh degree of protection. In case of a collision, the dimensions of the cockpit shouldn’t change, hencethe energy is consumed by the controlled deformation of the sacrificial structures. These sacrificial structures are defined by tubes/structures with closed profiles.
