9. G modeling

9.1. Characteristics of modeling

The law of behavior tested is” VMIS_CIN1_CHAB “documented in doc [R5.03.04]. It is a Chaboche law with nonlinear kinematic work hardening. The elastic parameters are as follows:

\(E(T)\), \(\nu (T)\), and \(\alpha (T)\)

The elastoplastic parameters are as follows:

\({R}_{I}(T)\), \({R}_{0}(T)\), \(B(T)\), \({C}_{I}(T)\), \({G}_{0}(T)\),, \(K\), \(W\), \({A}_{I}\)

Values of the parameters used:

Settings	\(T=20°C\)	\(T=500°C\)
\(E(T)\)	\(2.E5\) \(\mathrm{MPa}\)	\(1.E5\) \(\mathrm{MPa}\)
\(\nu (T)\)	\(0.\)	\(0.\)
\(\alpha (T)\)	\(1.E-5\) \({K}^{-1}\)	\(2.E-5\) \({K}^{-1}\)
\({R}_{I}(T)\)	\(300.\) \(\mathrm{MPa}\)	\(150.\) \(\mathrm{MPa}\)
\({R}_{0}(T)\)	\(100.\) \(\mathrm{MPa}\)	\(50.\) \(\mathrm{MPa}\)
\(B(T)\)	\(12.\)	\(5.\)
\({C}_{I}(T)\)	\(2000.\) \(\mathrm{MPa}\)	\(500.\) \(\mathrm{MPa}\)
\({G}_{0}(T)\)	\(45.\)	\(75.\)
\(K\)	\(1.\)	\(1.\)
\(W\)	\(0.\)	\(0.\)
\({A}_{I}\)	\(1.\)	\(1.\)
