IceBreakerSours I thought about using hyperelastic model, but the most essential feature in my simulation is plastic deformation. As far as I know Ansys do not allow to combine hyperelastic model with plasticity. But thank you for the link. This paper seems to be very valuable!
Thanks Petr for your answer. I didn't know that Ansys expects true stress-strain and extrapolates the curve.
Of course I use nlgeom,on and my displacement is applied in 100 steps (the analysis is transient so every step is divided into subsetps, the number of steps is rather random)

Hi,
I have to perform a simulation of tensile testing of PTFE(teflon). I've been given the data about the experiment (I have the stress-strain curve, Poisson's ratio, sample dimensions, strain rate). The problem is that this material is very ductile and the percent strain is equal to 246%. I...
