**v3.02.101** SSLP101 - Rate of energy restoration under plane stresses
============================================================================

**Summary:**

This is a static fracture mechanics test for a two-dimensional problem. We consider a cracked plate under plane stresses, the functionalities tested are:


* the :math:`G` energy return rate,


* the energy return rate calculated from the calculation of the stress coefficients :math:`{K}_{1}` and :math:`{K}_{2}`.

The advantage of the test is to compare the value of :math:`G` classical and the value of :math:`G` (IRWIN) obtained from :math:`{K}_{1}` and :math:`{K}_{2}`. It also makes it possible to test the invariance of the calculation with respect to integration crowns.

This test contains 3 different models: modeling A, which dealt with the calculation of the Rice integral, is no longer supported since version 3.
