摘要：In this work, the two-parameterJ-A(d)approach was applied to predict thefracture toughness of test single-edge-notched-bend (SEN(B)) specimens with different in-plane and out-of-plane constraints for two materials with different mechanical properties. The results show that for most SEN(B) specimens, the predicted fracture toughness agrees with the experimental data; thus, the capability and applicability of the two-parameterJ-A(d)approach are validated. The approach correctly predicts that the fracture toughness decreases with increasing in-plane and out-of-plane constraints. Compared with the prediction results of the three-parameterJ-Q-T(z)approach in the literature, theJ-A(d)approach has better prediction accuracy and wider application ranges. The calculation procedure of theJ-A(d)approach is also simple and convenient for engineering application.
