As a companion paper to our previous paper [Fatigue Fract. Engng Mater. Struct. 24, 243-254], this note provides further validation on the engineering crack opening displacement (COD) estimation equation based on the enhanced reference stress method against three-dimensional, elastic-plastic finite element (FE) results using actual tensile data of three typical ferritic steels exhibiting a wide range of Lüders strain. Furthermore, the resulting FE results are also compared with the GE/EPRI COD predictions. It is found that the proposed enhanced reference stress method gives overall more accurate and robust COD results than the GE/EPRI method, compared with the FE results.
