Hello Array nI wanted to circle back. I obtained some further information from a colleague. So Alfred Puck (of the Puck failure criteria) describes in his book Festigkeitsanalyse von Faser-Matrix-Laminaten that his failure theory can also be used for woven fabrics by splitting the fabric into two UD layers. Unfortunately the book is written in German with all the details and we can not translate and provide here, but that is the reference.nNow with that said, Puck requires at least 20 material properties to be used for woven, and these will be more sources of unknowns. and I might consider starting with a much simpler failure criteria. I hope this helps!nnRegards,nSea
