5. C modeling#
5.1. Characteristics of modeling#
The C modeling is performed on an axisymmetric 2D hardware point with STAT_NON_LINE.
5.2. Tested sizes and results#
5.2.1. Tested values#
The solutions are post-treated at point \(C\), in terms of:
vertical constraint \({\mathrm{\sigma }}_{\mathit{zz}}\);
horizontal deformation \({\mathrm{ϵ}}_{\mathit{xx}}\);
\({e}^{P}=\Vert {e}^{P}\Vert\) deviatoric plastic deformation norm
They are compared to an analytical solution (described in the next paragraph) in terms of maximum difference between \(t=0\) and \(t=20\). The results are summarised in the following tables:
\(Q=\sqrt{\frac{1}{2}\underline{\underline{s}}\mathrm{:}\underline{\underline{s}}}\phantom{\rule{2em}{0ex}}[\mathit{Pa}]\)

5.2.2. Comments#
The difference with the analytical solution is very small.
