A numerical study on the crashworthiness of corrugated conical tubes: energy absorption and impact performance

The crashworthiness of structures refers to their ability to protect occupants during an impact byabsorbing and dissipating the energy generated during a collision. One of the most critical designconsiderations in safety engineering, especially in automotive and aerospace industries, is to ensurethat energy absorption during a crash is maximized while minimizing damage to the occupants.Among the various energy-absorbing structures, corrugated tubes have emerged as an effectivesolution due to their enhanced performance in crash scenarios. This article delves into a numericalstudy on the crashworthiness of corrugated conical tubes, focusing on their energy absorptioncapabilities, deformation modes, and overall performance during an impact.
