I think the results would be circular. You'd need to input the non-linear properties of the material, but then the results would just reflect the properties that you input. You'd be able to get the same results with a simple hand calc.
Are you trying to figure out what the residual capacity would be with a certain fiber content? This is highly dependent on the particular fiber that you're using. For instance, 50lb/cy of Fiber A may have 25% higher residual capacity than the same dosage of Fiber B. The only way to really figure it out is with test results, thus the need to conduct testing.
You could probably model this with ANSYS or Abacus, but it would be extremely complex and a good subject for a doctorate thesis.
