結合力モデルを用いた衝撃損傷を有するCFRP積層板の圧縮試験解析

抄録

CFRP laminate subjected to out-of-plane load may have complex impact damage which may reduce the compression strength. This study aims to develop an analysis method that can simulate the damage propagation of CFRP laminate under out-of-plane indentation and predict the CAI strength. This paper shows the out-of-plane indentation and the subsequent in-plane compression test analyses using the FEM model of CFRP laminated plate considering the CZM. It was shown that the results obtained by the present method are appropriate.
