3D HASHIN VUMAT

[Materials Freak]

Dear researchers,
I want to model fiber-reinforced composite material for low velocity impact test and 4-point bending test. For that, I was looking for VUMAT for 3D Hashin criteria. Some of them are open-source and available on the internet, but since I have not used it before so I want to hear opinion from the experts in this community/forum about using 3D Hashin VUMAT in ABAQUS that are available online.
I would be extremely thankful if someone could share the VUMAT that worked fine for him.

Best regards

I would look for reseaech papers first but it’s not easy to find Abaqus subroutine codes there so any other source can be useful. Just have a look at it, try to understand it (based on the literature) and do some single element tests to see if it behaves as expected.
