9.1. Behavioral law and material parameters

The law of behavior tested “ROUSS_VISC”, is documented in doc R5.03.06. It is a law of elastoviscoplastic behavior that makes it possible to account for the growth of cavities and to describe ductile failure in steels. Values of the parameters used:

Settings	\(T=20°C\)	\(T=800°C\)
\(E(T)\)	\(210000\mathit{MPa}\)	\(100000\mathit{MPa}\)
\(\nu (T)\)	\(0.\)	\(0.\)
\(\alpha (T)\)	\(1.E-5{K}^{-1}\)	\(2.E\mathrm{-}5{K}^{\mathrm{-}1}\)
\({\mathit{SIGM}}_{1}(T)\)	\(500\)	\(450\)
\(F0(T)\)	\(5E-4\)	\(3E-4\)
\(D(T)\)	\(1.5\)	\(2.5\)
\(\mathit{BETA}\)	\(1.\)	\(1.\)
\({\mathit{SIGM}}_{0}\)	\(800\)	\(800\)
\({\mathit{EPSI}}_{0}\)	\(1.E-2\)	\(1.E-2\)
\(M\)	\(2\)	\(2\)
