Dear All,
I want to model crack growth in a plate using ABAQUS XFEM method. Here is my question about it: How to calculate Stress intensity factor in XFEM when crack growth in ON?
At this time, when I using ABAQUS XFEM with allowing for crack growth and request for SIF through History output request,
It says that SIF could not be produced when crack growth in XFEM is ON.
Best,

Hi Adel,
Currently, Abaqus doesn't support SIF or any contour integral for moving cracks. Abaqus supports it for stationary crack only. The contour integral are path dependent, so request at least 5 contours, ignore first 2 contours and take average of remaining 3.
Try different values of enrichment radius. Too small value of ER predicts larger and unrealistic values of SIF. ER should be some factors of element length to get reliable results.
All the best!
