| Popis: | During an impact collision situation, thin-walled tubes demonstrate excellent energy absorbing capability through plastic deformation and have been widely used in various structural applications. The present article discusses about the numerical investigations on the transverse crushing behavior and energy absorption performances of various stiffened cylindrical tubular elements. Numerical models were developed with ABAQUS/CAE® code to predict the deformation behavior of the proposed tubes under transverse impact force. The maximum energy absorption capacity that could be attained is with a stiffened cylindrical tube of fourth type. The final outcomes revealed that stiffened cylindrical tubes are remarkable in absorbing impact energy in transverse direction. |
