3.2 Cyclic Hardening Model
For the cyclic hardening model, three hardening models were used in this
paper: a kinematic hardening model determined from the tensile
stress-strain curve of X10CrMoVNb9-1 from RCC-MRx [44] and two
Chaboche combined hardening models [45-46] with parameters for Grade
91 at 600oC, proposed by Kyaw et al. [47] and Saad
et al. [48].
The kinematic hardening model is based on the average tensile
stress-strain curve of X10CrMoVNb9-1 from RCC-MRx [44], which is
given below:
