A unified approach to solving plane elasticity problems of stress concentration at the sharp and rounded corner cuts in elastic orthotropic body for symmetrical load is developed. First a relationship between the stress concentration and intensity factors for a semi-infinite rounded and sharp cuts is obtained by the method of singular integral equations. These dependencies can be interpreted as asymptotic solutions for finite bodies with notches small radius of curvature at the tips. The stress intensity factors at the corner tip of double-link broken crack in orthotropic plane is identified. Found analytical solutions of distribution of stresses in anisotropic (orthotropic) plane with a parabolic semi-infinite cut for a three main types of deformation, when asked at infinity asymptotic stress field, which includes stress intensity factors at the tips of the respective semi-infinite crack.
