Study of Energy Absorption of Combined Model of Cylindrical Compression-Expansion Tube and Thin Cylindrical Tube

摘要：

A thin cylindrical tube that is mainly used as an automotive body structure absorbs energy while generating local wrinkles. Hence, the first peak of the compressive load is produced in the early stages of deformation, and then, the load amplitude is cut. When the length of this tube is increased, no wrinkles are generated, but the Euler buckling on the entire bend is observed and the energy absorption decreases significantly. In this paper, we show that a combination of a cylindrical compression-expansion tube and a thin cylindrical tube favorably affects the energy absorption. Therefore, it is possible to improve the energy absorption of this design.
