Hysteresis for hyperelastic material

Hysteresis for hyperelastic material

Hysteresis for hyperelastic material

(OP)
Hello all,

I would like to ask if you know of any good reference or method on how to choose the parameters defining hysteresis for hyperelastic material models. Namely, the stress scaling factor, the creep parameter, the effective stress exponent, and the creep strain exponent.

I want to simulate the loading and unloading of a rubber piece.

Thanks in advance!
