Article Preview

The purpose of this study is to verify the validity of sheet buckling design based on the effective width theory investigation of impact crushing properties in high strength steel sheets. We clarify the need to make full sections effectively without elastic buckling occurring and consider the application of the effective width theory under high speed deformation. We report our findings of our investigation into the sheet buckling phenomenon with numerical simulation by varying deformation strain rate, mechanical property of material and member configuration. The results demonstrate that, with increasing crush speed, the cross section of a steel sheet become effective, while there is a high possibility of the buckling phenomenon that does not function as efficient impact absorption and is not evaluated with the existing theory.
