Originální abstrakt
A bi-material notch composed of two orthotropic parts is considered. The radial and tangential stresses are expressed using the Stroh-Eshelby-Lekhnitskii formalism for plane elasticity. The potential direction of crack initiation is determined from the maximum mean value of the tangential stress and the local minimum of the mean value of the generalized strain energy density factor in both materials. The matched asymptotic procedure is used to derive the change of potential energy for the debonding crack and the crack initiated in the determined direction.
