Description
Summary:•The fictitious notch rounding concept is applied to U-shaped notches in orthotropic bodies.•The fictitious notch radius is determined in closed form.•T effect of the elastic properties of the material is crucial. In this short contribution, the fictitious notch rounding concept is applied to U-shaped notches in orthotropic bodies. Using the normal stress criterion, the fictitious notch radius is determined in closed form. It is found that the fictitious radius strictly depends on the actual notch radius, the microstructural support length and the elastic properties of the material, the latter playing a crucial role.
