“…Even though this issue is solved with a temperature history-independent formulation of the Armstrong-Frederick kinematic hardening rule based on a similarity equation under temperature variation by Ohno and Wang [10,11], their approach has not prevailed. The Chaboche-type time-and temperature-dependent plasticity models were widely applied to describe the material behavior under cyclic thermomechanical loading conditions for different materials and material classes, e.g., aluminum alloys in [12,13], forged and cast steels in [14][15][16][17], nodular cast iron in [18,19], copper in [20] and nickel-based superalloys in [21][22][23][24][25][26]. Further extensions to the Armstrong-Frederick kinematic hardening law were proposed to describe better non-proportional hardening, e.g., [24,27], strain range memory, e.g., [28,29], as well as cyclic kinematic hardening and softening, e.g., [3,30].…”

“…Particularly, the Chaboche unified viscoplastic constitutive model can reasonably express the stress-strain response behaviors of many materials in complex loading conditions at elevated temperatures. [27][28][29][30][31] The movement of yield surface was expressed by the nonlinear Armstrong-Frederick kinematic hardening rule 32 ; then, the rule was further modified to describe the emerging stress-strain behaviors under new loading conditions. For example, the dynamic recovery term was modified to express the ratcheting behavior of materials that can cause mean stress under symmetrical tensioncompression cyclic loading.…”

“…In the constitutive model of cast iron, Szmytka et al 19 introduced specific flow criteria. Bartošák et al 20 improved the hyperbolic sine function flow criterion and temperature-dependent kinematic hardening equation. Later, Wu et al 21 developed a constitutive model coupling viscoplasticity and damage to accurately predict the high-temperature viscoelastic behavior of cast iron materials for exhaust pipes.…”

“…However, various material fatigue tests are needed, such as isothermal Low Cycle Fatigue (LCF) and Out-of-Phase TMF (OP-TMF). In particular, a creep-fatigue test with a long time (>300 s) of high-temperature holding 20 is needed to characterize material viscosity. In addition, for the damage life of cast iron, Gocmez et al 22 proposed a prediction method of cyclic dissipative strain energy and considered the temperature and stress correction factors to couple high temperatures (creep, oxidation) and pure fatigue damage.…”
