Crashworthiness analysis of corrugations reinforced multi-cell square tubes

Multi-cell tubes are widely used as energy-absorption components in transportation field due to its high energy absorption capacity and good weight efficiency. However, with the increase of vehicle speed, people have high requirements for safety, and therefore, the crashworthiness performance of multi-cell tubes should be further improved. To this end, we proposed a new type of multi-cell circumferentially corrugated square tubes (CCSTs) by...
