Abstract
The dynamic behavior of a thin-walled circular tube under high-velocity impacts was investigated by performing a finite element analysis (FEA) and an experiment. The FEA for a thin-walled circular tube subjected to an axial impact revealed the effect of the impact velocity. The results suggested that an increase in the initial impact velocity enhances the absorbed energy through compressive deformation. High-velocity impact tests on aluminum alloy circular tubes confirmed the energy absorption characteristics indicated by the FEA.
