crack propagation in abaqus cae
(OP)
Howdy.
I have been able to model a crack and get accurate SIF values... but does anyone know how to propagate a crack using CAE? Cheers.

I think in abaqus, you can model the different crack length and find the J-integral corresponding. Then, using fatigue criterion to make comparsion with experimental results.

The steps to model crack propagation are explained in the documentation. For v6.5 see
ABAQUS Analysis User's Manual -> 7.9.3 Crack propagation analysis

The crack can propagate only along a "known" path, modeled as bonded contact surfaces. For more details and examples, please see the ABAQUS documentation.
