Hyperelastic material - cyclic behavior

[MrusTgr88]

Hi everybody,

I have used Marlow material hyperelastic model to model elastomer. Under static load it works fine. But when I have assigned in Suboptions data for hysteresis I got the ERROR:

***ERROR: THIS KEYWORD IS NOT AVAILABLE IN Abaqus/Explicit
LINE IMAGE: *hysteresis

Does this mean that I can't define hysteresis behavoir of elastomer in Abaqus/Explicit?

Can you work with modeling the Mullins effect? *Hysteresis is not supported with Abaqus/Explicit.

Yes, that was an option I was thinking about too. I was reading Abaqus manual fro the last 3 days, but I am not sure what to do. I have stress-strain data from the experiment on elastomer. Experiment was performed on 300x300x24.5 mm elastomer, monotnic load only in compression. And in the next cuople of days we are going to do the same for cyclic load. Si I wanted to try the simulation before the experiment.

Should I use test data or directly constants for input for Mullins effect? And I am not sure when I input test resulta should I define parameters r, m, beta too?
