*FABRIC material in Abaqus

*FABRIC material in Abaqus

(OP)
Hi all,

I would like to simulate stamping of composite laminates (I start with a simple lamina!).
The goal is to be able to see the re-orientation of fibers, eventually the appearance of wrinkles. Not much more in a first time...

To do that, I tried in a first approach to model it with classical elastic lamina material. Results are bad, as we expected.
Now I am trying to couple elastic elements (with resin's characteristics) to elements having a *FABRIC material assigned to it (with the glass fabric characteristics). These are superposed S4 elements sharing the same 4 nodes.

It works pretty much, but the problem is that *FABRIC material does not have any bending behavior (from what I understood). Only traction, compression and shear. Thus, a lot of undesired (not real) wrinkles appear...
What can I do to take into account the fact that fibers have a bending behavior? Should I use VFABRIC routine (I would like to avoid this...) or do you have any other idea? Or should I try a totally different approach?

Thank you very much.
Best regards,


Max
