摘要：
The notch stress intensity factor (N-SIF) is widely used to characterize the notch stress concentration under different crack opening angles. At present, the evaluation formula of notch stress intensity factor is too complicated and inconvenient for engineering applications. Therefore, based on the isotropic V-notch plate, this paper introduces the concept of singular strength factor as(i), and further presents the notch stress field and the simple evaluation formula of N-SIF for double edge V-notched orthotropic thin plate. The formula is simple in form and clear in physical meaning. After numerical verification and verification with the evaluation results of traditional literature, the results show that the semi-analytical formula proposed in this paper has a wider application range and can be applied to different materials and loads simultaneously.
