“…The modified model in Eq. (2) is referred as GTN model, which has been implemented in ABAQUS code and widely used to predict and simulate ductile crack growth and fracture resistance behavior of different specimens, material interfaces and welded joints [10,[20][21][22][23][24][25]. In this study, GTN damage model was used in the FEM simulations to obtain the crack growth resistance curves and ductile fracture toughness of the two interface regions in the Alloy52M DMWJ with different initial crack locations.…”

“…For simulating this process, the damage mechanics model, such as the Gurson-Tvergaard-Needleman (GTN) model [17][18][19] was developed. This model has been widely used in simulating the ductile crack growth and fracture resistance behavior for different specimens [20], material interfaces [20,21] and similar metal welded joints [22][23][24][25][26]. The fracture resistance curves of a DMWJ also have been simulated using the GTN model by authors [10].…”

“…The initial voids volume fraction has been determined from microstructural observations (Section 2.2) and methods recommended in the literature [27,[33][34][35]. In this work, the initial void volume fraction is estimated by the inclusions volume fraction, which corresponds to f 0 = 0.0015.…”
