17.1. Characteristics of modeling#
The law of behavior tested is” VMIS_JOHN_COOK “documented in doc [R5.03.02]. It is a Von Mises law of Johnson-Cook isotropic work hardening. The elastic parameters are as follows:
\(E(T)\), \(\nu (T)\), and \(\alpha (T)\)
The elastoplastic parameters are as follows:
\(A\), \(B\), \(C\), \({N}_{\mathrm{PUISS}}\), \({M}_{\mathrm{PUISS}}\),, \(\mathrm{EPSP0}\), \(\mathrm{TROOM}\), and \(\mathrm{TMELT}\)
