CFRP接着接合部の破壊じん性評価に及ぼす接着層の変形の影響

抄録

The purpose of this study is clarifying the effect of deformation of adhesive layer on evaluation of fracture toughness in adhesively bonded joints and identifying crack length and energy release rate GII by finite element method. The result of numerical analysis demonstrated that crack length and energy release rate GII were identified accurately by using equation that is added the section of shear deformation to conventional compliance equation, and critical compliance that is obtained by connecting the beginning point to critical point of load displacement curve.
