CFRP 구조 부재의 시뮬레이션 동적 거동에 관한 연구

다국어 초록 (Multilingual Abstract)

The structural members like transport machine are largely using shape or hollow steel member that has definite shape at present. Especially, structural members used vehicle support variously components and absorb impact energy to protect passenger when crash happen. The latest structural members are being developed in the lightest of light weight and stability because of these features. One of composite material, that is, CFRP has high specific strength and specific stiffness. It makes them attracted. In order to predict these fracture shape and energy absorb feature of CFRP members, there are many studies which are being progressed. But there are lots of differences between FEA Program and experiment. In this study, we do a impact simulation of CFRP square member using finite element analysis program Ls-Dyna in order to predict fracture shape and energy absorb feature of CFRP member. Also, we make square member shape of CFRP and do an impact experiment. After the experiment, we compare result of FEA Program with experiment result and consider fracture shape and energy absorb feature of CFRP members.
