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

This test case aims to validate the calculation of the energy return rate in non-linear elasticity:


*
    *
        * The A and B models make it possible to validate the calculation of G in plane deformations, in pure mode 1 and in mixed mode


        * C modeling validates the calculation of G axisymmetrically, in pure mode 1.


        * D modeling validates the G calculation following a thermo-mechanical calculation.
