Reply To: Is there a way to use a bilinear orthotropic model?

Regarding the other tools. Granta, ACP. First Granta has material data, but in the end, it still has to write out a material model that Ansys can utilize. I have not seen any material with such behavior. Regarding ACP, it is just a pre/post tool and not a solver so it too won't have any material model. Material Designer is a pre/post to MAPDL as it runs RVE simulations in the background to compute material properties using homogenization. It does have a non-linear capability in beta, which can export stress-strain curves. This would be a micro-mechanical model representation, so if I put in plasticity or even damage, then the RVE model will use it, but note that convergence could be a problem especially when damage is included.. So in the end you may result in some stress-strain curves that you could potentially apply at the macro level via the material models such as Hill or ANISO or others. You can not take the curves and use them directly. We can for response function in hyperelasticity, but that is a digression. I just wanted to point this out. What are the materials if you can elaborate. Thank you.
