Hi Mohammaed,

I think Mehmet sir is right. You can always use FC command in postprocessing for different failure criterions. If you want to get faliure indices which are not available in FC command then you can write macros to obtain those. You have to store stress-strain data through element table. then you can easily calculate failure indices whichever you want. you have to write those failure criterions in macros.

Dear Mehmet Firat , Thank you for your guidance. I hope that I can find the book which you proposed.

Dear Yagnik Kalariya . Thank you a a lot for your attention and guidance.
