3次元異方性—等方性接合体の界面端近傍における特異応力場解析

抄録

Recently, dissimilar material joints are used in industrial products for improving functionality and strength. In this study, the joining strength of adhesive joints of carbon fiber composite material which is an anisotropic materials are investigated through a conservative integral. The order of singularity and the angular function are calculated using the eigenvalue analysis based on finite element method. Intensity of stress singularity is calculated using a conservative integral. By using these analysis methods, quantitative evaluation of stress singular field at the edge of interface in the adhesive joints of carbon fiber reinforced plastic is conducted.
