•Fracture of U-notches under mixed mode loading has been assessed using Jcr criterion.•The expression for evaluation of Jcr can be applied for specimens loaded under mixed mode.•Finite element software ANSYS has been used for evaluation of the J-integral.•Both SED and Jcr criteria can predict the fracture load of U-notches under mixed mode loading very well.
The main aim of the paper is to show that the expressions proposed for evaluation of the critical value of the J-integral in notches (Jcr) can be applied for mixed mode loading, too. So, fracture load of plates weakened by U-notches under mixed mode loading has directly been evaluated by J-integral. The J-integral for plates with different mode mixity has been evaluated by using the finite element software ANSYS. Then the fracture load has been assessed by means of J = Jcr. The results of fracture load using J-integral have been compared with experimental data for martensitic steel plates taken from the literature and good agreement was found.
