Hello ,
im working on crack propagation ,i want to model a 2D crack using xfem thus
i want to find the stress intensity factor but when i submit I find the
error represent on the figure .
Cordialy .

HelloThere is a point , xfem method in abaqus just only CAN calculate SIF ON the 3D model.You must use contour integral for your simulation.Regards

 Salam,
If you would to calculate K, you need to calculate with integral J, not with XFEM, the crack must to be stationary, not to propagate.
Best regards.

Re:

SOUFIANE
hello ,  thanks for your reply, i try to use xfem because I saw several papers used the xfem method for case 2d and  i think they used a subroutine or something else .
 Best regards   .
