“…Wang et al 21 demonstrated that the K‐R model is more suitable than the Norton model for describing the creep behavior such as creep rupture strain and creep rupture time of UNS N10003 alloy. Choi et al 22 used the K‐R model to accurately capture the creep behavior of 617 alloy at high temperature under a wide range of stresses at 800°C.…”

In order to accurately predict the minimum creep rate under the actual working conditions of compacted graphite cast iron cylinder head, this paper conducted creep experiments in the temperature range of 723.15–823.15 K and the stress range of 100–300 MPa. The creep damage evolution and damage mechanisms under test conditions were also analyzed. Then the data fitting performances were analyzed and compared from three aspects: the optimization‐seeking algorithm, the form of the objective function and the construction of the creep constitutive model. Finally, the chosen optimization algorithm combined with the proposed objective function and creep constitutive model resulted in 100% of the predicted values within the 3 times error band and 26.67% of the predicted values within the 1.5 times error band. This improves the prediction accuracy while reducing the effect of data overfitting.

“…10 Saberi utilized Liu-Murakami damage model to assess the life of blade-disk attachments. 11 Praveen 12 and Wang 13 used Kachanov-Rabotnov damage model to predict the creep damage behavior of 316LN steel and UNS N1003 alloy, respectively. Recently, a Sinh damage model was originally proposed by Stewart 14 and then improved by Haque and Stewart.…”

In order to accurately predict creep deformation and damage evolution of nickel-based superalloy GH4169, a novel damage constitutive model, that is, TTC CDM-based model, was proposed based on TTC relations and continuum damage mechanics (CDM). This model combined the best features of the TTC relations and CDM. The recently developed TTC relations were intrinsic relations between threshold stress, tensile properties, and creep behavior and exhibited better prediction ability than Wilshire equations. It was determined that the model accurately predicted the minimum creep rate, rupture time, creep deformation, and damage evolution process of GH4169. Microstructural study has revealed that the creep fracture mode gradually converts from intergranular brittle fracture to transgranular ductile fracture as the stress decreases. Furthermore, the nonlinear creep damage accumulation effect was also revealed by the novel model.

“…The comparative research was reported by Rouse [15], where the hyperbolic sine creep function and the power law-based models, including Liu-Murakami and Kachanov-Robotnov, were compared to show the effectiveness and conservativeness of each model. For instance, the Kachanov-Robotnov creep model is more suitable than the Norton function when simulating the creep behaviour of Nickel-based alloy under a high-temperature environment [16]. The Liu-Murakami creep damage model is also able to calculate the creep crack growth life of 316H steel under the extended finite element method (XFEM) framework [17].…”
