Hi Steve,
I am using the material (polycaprolactone) for FEA models which exhibits viscoelastic properties (figure of cyclic from 10% strain control shows viscoelastic behaviour from second cycle). I have already inverse fitted elastic properties of material with Ogden 2nd order. Now, I have to inverse fit viscoelastic properties of material. Do I have to start from 2nd cycle (which demonstrates viscoelastic properties while loading) followed by unloading? Or I have to inverse fit from beginning (loading) followed by unloading and then loading (2nd cycle), figure is enclosed?Fig1.zip
Regards,
Nataliya
