Hi Hélio,

as commented Ahmad, I took the XFEM module with Prof. Moës during my master studies too. In case you want to dive into the topic, I should recommend you:

- Original paper:

Moës N, Dolbow J and Belytschko T. A finite element method for crack growth without remeshing. Int. J. Numer. Methods Eng. 1999; 46(1):131–150.

-Review:

-Book (Chapter 11):

-Matlab code: (I used this code as a starting point for my master thesis)

I hope it helps.

Cheers,

Thank you all for your help.

I will dig the materials.
