v6.03.505 SSNP505 - Multi-cracked bitraction-shear plate with X- FEM

Summary:

The objective of this test is to validate the multi-crack approach with X- FEM and junction. A plate in plane deformation is stressed by bi-traction and shear. Eight cracks are introduced in the center of the plate, two of which have a junction. We then use RAFF_XFEM to refine around the crack bottoms and CALC_G to calculate stress intensity factors.

A first test makes it possible to validate the contactless approach by comparing stress intensity factors with a semi-analytical solution. Then it is shown in a second test that the addition of contact, which corrects certain interpenetrations, influences the results.
