Abstract:In this study, theoretical bi-elastic constant ƒ¿ for an interface crack between dissimilar anisotropic composite materials has been obtained. The obtained theoretical solution has been settled to the equation which defines conventional ƒ¿ for an interface crack between isotropic materials, when it brings each material property close to the characteristic of isotropic composite ones. The remarkable conclusion is to determine ƒ¿ regardless of the direction of the boundary surface, if angle difference between anisotropic strongest axes in both sides is fixed.
