4. B modeling

4.1. Behavioral law and material parameters

The law of behavior tested “LEMAITRE”, is documented in doc R5.03.08. It is a non-linear viscoplastic law of LEMAITRE with no threshold. Values of the parameters used:

Settings	\(T=20°C\)	\(T=500°C\)
\(E(T)\)	\(1.E5\mathit{MPa}\)	\(2.E5\mathit{MPa}\)
\(\nu (T)\)	\(0.\)	\(0.\)
\(\alpha (T)\)	\(2.E-5{K}^{-1}\)	\(2.E-5{K}^{-1}\)
\(N(T)\)	\(10.8\)	\(8.0\)
\(1/K(T)\)	\(6.9E-4{(\mathit{MPa})}^{-1}\)	\(4.0E-4{(\mathit{MPa})}^{-1}\)
\(1/M(T)\)	\(0.102\)	\(0.05\)

4.2. Tested sizes and results
