Material Definition from Stress-Strain Curves
Material Definition from Stress-Strain Curves
(OP)
Hello all,
I have loading-unloading stress vs strain curves for golf ball cores at three different strain rates. I also have Hysteresis(kJ/m3) vs Strain rate curves.
Can somebody give me a step by step guide as to how I can use these to input a hyperelastic and viscoelastic OR hyperelastic with hyteresis material model? Which one is best/simplest? Do I need anything else?
I have read alot about the BB model, which seems popular. How do I get/use this?
Any tips are greatly appreciated,
Regards
Jamie Rowe
