Abstract
- In this work, the two‐parameter J‐Ad 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‐parameter J‐Ad 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‐parameter J‐Q‐Tz approach in the literature, the J‐Ad approach has better prediction accuracy and wider application ranges. The calculation procedure of the J‐Ad approach is also simple and convenient for engineering application. [ABSTRACT FROM AUTHOR]
