Hallo,

I want to use the BB-model in Combination with Mullins effect, but Im not sure which input data I need for MCalibration to fit the parameters properly.

I would test the material first on different strain levels with one loading and unloading cycle each (like described [URL= https://polymerfem.com/content.php?77-bergstrom-boyce-model]herel[/URL]) and after that I would do up to 10 cycles for every strain level (with a new specimen). I would take both the virgin loading and unloading cycles and the 10th cycle of every strain level as input data. Would that work? Do I have to consider something for the time stamps for the programme to know which curves are affected by Mullins effect?

I tried to use Data like in the following picture, but I couldnt get a proper fit with MCalibration:

Thanks!

Best regards
