**v3.04.319** SSLV319 - Plane propagation of a semi-elliptical crack
=======================================================================

**Summary:**

The purpose of this test is to validate the plane propagation of a crack by observing the displacement of the crack bottom during propagation.

This test involves a pavement with a flat semi-elliptical opening crack, subjected to a tensile force.

The crack is represented by the X- FEM method and the propagation simulated using the PROPA_FISS command.

We are going to compare the results to an experimental solution.

This test contains four models:

Modeling A uses the MAILLAGE method of the PROPA_FISS operator.

B modeling uses the GEOMETRIQUE method of the PROPA_FISS operator.

C modeling uses the GEOMETRIQUE method of the PROPA_FISS operator, with cohesive elements. Operation DETECT_COHESIF is used to determine the advance of the front.

The 3D modeling uses the SIMPLEXEde method the PROPA_FISS operator.
