Original abstract

A bi-material notch composed of two orthotropic parts is considered. The stress components and the strain energy density are expressed using the Stroh-Eshelby-Lekhnitskii formalism for plane elasticity. The stress singular exponents and corresponding eigenvectors are the solution of the eigenvalue problem leading from the prescribed notch boundary and compatibility conditions. Generally, there is more than one solution of this eigenvalue problem and consequently the stress intensity factors. The potential direction of crack initiation is determined from the local minimum of the mean value of the strain energy density factor in both materials. Following the assumption of the same mechanism of the rupture in the case of the crack and the notch, an expression for the critical values of the stress intensity factor can be obtained.
