Hi all
I would like to implement XFEM failure criteria into an RVE model. Could someone please send me the basic steps or the necessary output cards required for a successful implementation of the failure criteria?
Thank you !
Which version of Hyperworks you are using?
Regards
Rahul R
I am using Hyperworks 13.0
Avijit R
i have also installed hyperwork 14.0 . Please guide me through some basic steps.
You mean to say XFEM for Composites?
Yes, i would like to analyze crack propagation in fiber and matrix of the composite structures (at the micro scale) by applying different loading conditions. I would like to proceed by defining different material property for fiber and matrix and observe how and where the crack is initiated and the path taken by it. I have alreadycreated a simple RVE (representative volume element) model.
Looks like this feature is under development (PLYXFEM). Will update once this feature is available.
Okay but could please share any example models where XFEM has been implemented ? would really appreciate it.
Please find attached two examples as requested.

Thank you very much but unfortunately I am not able to import it in Hyperworks 14. It shows 'the file being opend for reading doesn't exist'.
On the other hand, it perfectly opens in HW 13. But then i do not get any output results (for eg. the drop test). Could you please help me out with this?
Could u please share the output cards in radioss necessary to visualize the crack formation in the elements (phantom elements) ? Thanks a lot.
Any help or guidance on the same issue. I couldnt find relevant example of Crack modeling in Altair.
