v3.02.319 SSLP319 - Propagation of two X-FEM through cracks stressed in mode I

Summary:

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

It is a \(\mathrm{2D}\) plate containing two cracks, each with a single bottom. Several propagations are calculated by the PROPA_FISS operator. We check that the stress intensity factors of the propagated cracks are correct for propagation in \(I\) mode.
