Relationship between stress concentration and stress intensity factors in sharp or rounded V-notches in orthotropic plane

By using the singular integral equations of the plane problem of the theory of elasticity for anisotropic body with cracks, integral equations for an orthotropic plane containing curvilinear holes with rounded vertices have been constructed. By using the limit transition when the radius of curvature of vertex tends to zero, the stress intensity factors in sharp vertices of the holes have been found.
