**v3.02.318** SSLP318 - Propagation of a non-through X-FEM crack solicited in mode I
============================================================================================

**Summary:**

The purpose of this test is to verify that operator PROPA_FISS treats multi-crack cases correctly.

This is a :math:`\mathrm{2D}` plate containing a single crack composed of two crack bottoms. Several propagations are calculated by the PROPA_FISS operator. We check that the stress intensity factors of the propagated crack are correct for propagation in :math:`I` mode.
