8. G modeling

8.1. Behavioral law and material parameters

The law of behavior tested “VISC_TAHERI”, is documented in doc R5.03.05. It is a law of (visco) -plastic behavior modeling the response of materials under cyclic plastic loading, and in particular making it possible to represent ratchet effects. Values of the parameters used:

Settings	\(T=20°C\)	\(T=500°C\)
\(E(T)\)	\(200000\mathit{MPa}\)	\(180000\mathit{MPa}\)
\(\nu (T)\)	\(0.\)	\(0.\)
\(\alpha (T)\)	\(1.E-5{K}^{-1}\)	\(2.E\mathrm{-}5{K}^{\mathrm{-}1}\)
\(S(T)\)	\(450\)	\(400\)
\({C}_{\mathit{INF}}(T)\)	\(0.065\)	\(0.060\)
\(C1(T)\)	\(-0.012\)	\(-0.010\)
\(B(T)\)	\(30.\)	\(20.\)
\(M(T)\)	\(0.1\)	\(0.15\)
\(A(T)\)	\(312\)	\(200\)
\(\mathit{ALPHA}(T)\)	\(0.3\)	\(0.25\)
\({R}_{0}(T)\)	\(72\)	\(50\)
