Can somebody assist me with modelling the crack propagation with XFEM (Abaqus) in connection with contact problems?

Hello,

I want to arrange a crack propagation in a screw thread. Therefor I use two dimensional axissymmetric elements in Abaqus 6.12-3 (it is the first version, that allows XFEM in axissymmetric models). The boundaries of the screw thread are on the one hand the symmetry axis, on the other hand the contact to a nut thread that is hold in vertical direction. Thus, there are two nonlinear problems: 1.) the contact problem and 2.) the XFEM crack growth.

1.) Arranging the analysis of the contact problem without crack growth works thoroughly.

The tasks involved in this position include geometrical analysis of the
3D images, generation of datasets which are suitable for the computations
(meshes, level-sets fields ...), computations using novel numerical techniques
(X-FEM and related)
