Abstract: Thin walled tubes are used for various applications across the industries. Application of thin walled tube for automotive crush can as an energy absorber is covered in this study. Automotive vehicles play a significant role in modern transportation. The deaths and injuries caused by car accidents have become a major concern for society. Engineers and scientists have been working tirelessly in recent years to improve overall vehicle safety. Crumple zones have been introduced to reduce the impact on and structures and travelers during a collision. To improve crashworthiness and energy absorption capabilities, more emphasis has been placed on the development of new designs of energy absorption devices such as crush cans and bumper beams. The crash analysis simulation and results can be used to evaluate the crashworthiness of the current design as well as to investigate ways to improve it. This type of simulation is an essential part of the design process and can eliminate the need for costly destructive testing. In this study, a FE model of thin walled tube as a crush can is proposed for axial compressive load and experimentally validated.
