Reply To: XFEM Crack growth of internal crack in a 2D plate

Hi,

Thanks for the link.

I already covered almost all the available reference in ANSYS documentation to figure out my problem including the link shared. Unfortunately, there is no clear indication of how to model the multiple crack fronts/ tips during fatigue crack growth in these documents (Some information is available for computing SIF under quasi-static case, which I already implemented in my validation codes). The examples provided under ANSYS help pages also consider only one crack front/tip, which is quite simple compared to my problem. I am looking for something from APDL developement as the error resulted doesn’t make sense as I am specifiying only Life-cycle method in my codes. Also there is no mentioning of XFEM based fatigue crack growth is limited to only one crack front/tips under the limitations/ characteristics of ANSYS help page (https://ansyshelp.ansys.com/public/account/secured?returnurl=/Views/Secured/corp/v242/en/ans_frac/fracfcgxfem.html) or Fracture analysis guide (I know this is the pdf version of the help webpage). 

Thank you.

Regards,

Jose Mishael
