To ensure the safety of passengers and minimize damage in the event of an accident, it is crucial that a crash-resistant structure be developed. In this paper, square tubes made of aluminum and mild steel served as the primary structural components. Foam of varied densities was packed inside the tubes to absorb and disperse the force of any impacts. The thickness of the square tubes used, in addition to the materials and foam filling, greatly affects the crashworthy structure's ability to resist energy. Two different square tubes, 2 mm and 3 mm in wall thickness, were used in the experiment. The performance of the framework is also affected by the foam insulation. Impact energy may be dispersed and absorbed more effectively if different densities of foam are used in different parts of the product. High-density foam is used where more resistance to impact is needed, while lowdensity foam is used where more cushioning is required. The crashworthy structure developed is the result of a careful balancing act between the materials, thicknesses and foam filling used.


The development of structures that can withstand and mitigate the effects of crashes is a crucial component of the field of vehicle safety engineering. The purpose of crashworthy structures is to endure the energy produced during a collision event and to safeguard the vehicle's occupants. The principal objective of crashworthy structures is to mitigate the likelihood of harm or fatality to occupants engaged in a vehicular impact. The design of crashworthy structures involves several factors that need to be taken into account (Hallowell et al., 2013; Nahum and Melvin, 2002; and NHTSA, 2021). The aforementioned factors encompass the selection of materials and the implementation of foam filling for the purpose of collision absorption and
