5. G modeling#
5.1. Characteristics of modeling#
Tested behavior: PlasticityTh.MFront (which imports Plasticity_Sy.MFront). Von Mises” elasto-plastic law, comparable to VMIS_ISOT_LINE, with the effect of temperature.
Modeling similar to that of test HSNV100J. The elastic limit varies according to the temperature as follows: \({\sigma }_{y}=400.0-4.0T;\)
the other material properties are constant: \(E=200\mathit{GPa},\nu =\mathrm{0,3},{E}_{T}=50\mathit{GPa}\)
5.2. Tested sizes and results#
The reference solution is analytical (cf. [V7.22.100]):
