The singularities of collinear cracks both in anisotropic single mediumand at the interface of anisotropie bimaterials are studied by combining Stroh formalismand the analytic function method.The formulae for calculating the field potential andstress intensity factor(SIF)are obtained.It is found that the field potentials areexplicitly related to material matrix L and the in-plane and anti-plane fields can beseparately calculated when orthotropic bimaterials are considered.
