A new model, accurate and easy-to-apply, has been proposed to predict the residual strength for metal plates intact or with different damage degrees. In this model, we introduced the damage degree factor (DDF) to quantify the initial damage condition of a plate. The middle crack tension (M(T)) tests and multiple site damage (MSD) tension tests were performed on plate specimens in aluminum alloy LY12-CZ and 2524-T3, respectively. For various damage degrees, the predicted results of this new model showed an improved correlation with test results compared to the net section yield criterion, K-apparent criterion and Duong’s method.
