چکیده:

Thin-walled structures have been widely used as energy absorbers in crashworthiness applications such as automobile and aeronautical industries to protect passenger from severe injury. This paper investigates the energy absorption response of thin-walled conical tubes with shallow spherical caps under quasi-static axial loading. Satisfactory agreements were generally achieved between the finite element model andexperimental deformed shapes, load–compression and energy-compression. Finally, the effect of semi-apical angle on the behavior of conical tubes with shallow spherical caps was investigated. The practical outcome of the study is design information for the use of thinwalled conical tubes with shallow spherical caps as energy absorbers in aerospace applications to design reentry sounding rocket based on conical tube withshallow spherical caps
