Hello all,

I want to add hysterisis in my hyperelasticity model. However for all the hysteretic factors stated in ABAQUS (stress scaling factor, creep parameters and the two exponents) I dont have a closed form solution that could guide me through finding them.

Does anybody know of any source where this can be possible?

Thanks

I strongly recommend using the [URL= http://polyumod.com/download ]MCalibration [/URL]for that.
It solves that problem very quickly and easily!

Thanks.

Already sent a question asking for specifics.

Thanks again!

Hello again,

is there any parameter that I have to set to a specific value if I want a strain-rate independent hysteresis material model in ABAQUS? For the strain rates of interest my hysteresis loops are pretty stable so Id like to not have this as a potential factor that affects my results.

Thank you!
