Crack-Fracture

[MaxMechanical15]

I am wondering what would be the best strategy to model the following case: a crack is propagating in a pipe under the internal pressure due to the fluid contained into it until the pipe fractures.

Can it be modelled
1)using a cosimulation:
With a XFEM crack (Abaqus implicit) on a zone of the pipe with damage traction separation laws>MAXS damage evolution
plus a ductile model ( initiation and evolution) (Abaqus explicit)
Or

2)using a ductile model (initiation + evolution) Abaqus explicit
Plus the element deletion method for the crack
Or

3)does it exist another way to do it ?
Many thanks for your suggestions.

I would go with XFEM, not sure you can use an explicit material model with XFEM though.
