Summary of results
======================

This test case offers very satisfactory results compared to the analytical solution, less than 7.10‑5% with a low number of iterations (1 or 2 iterations). The solution is obtained from a linear equation in the case of a linear strain hardening curve under tension, but the resolution uses a Newton algorithm in a more general framework.

It is possible to note the hardening of the tensile criterion which takes place during loading, causing a reduction in stress (component :math:`\mathit{xx}`, :math:`\mathit{yy}` and :math:`\mathit{zz}`) which is also equal to the hydrostatic stress.
