티어링 튜브 컬의 변형 거동 예측 기법 연구

초록

This paper discusses the analysis of the curl deformation behavior when a dynamic force is applied to a tearing tube installed on a flat die to predict the energy absorption capacity and deformation behavior. The deformation of the tips of the curling strips was obtained when the curl tips and tube body are in contact with each other. A formula describing the mean curl radius is proposed and verified using the curl radius measurement data of collision test specimens.
