Crashworthiness analysis of a straight-tapered shrink tube

This paper proposes a new straight-tapered shrink (STS) circular tube, which is planned to be applied on railway coupler for energy absorbing and overload protection. Quasi-static experiment and finite element (FE) simulation were adopted to investigate the crashworthiness performance of the STS tube. In the FE analysis we found that the compressive material properties were more suitable for accurately modeling the STS tube. The results showed...
