Material Law Characterization with RADIOSS

Hello,

I am trying to use Hyperstudy to perform an inverse analysis to characterize a rubber. But in the tutorial (p367 attached pdf) I used, there is an .xy file required (Stress-Strain data points).

How can I switch my type file .txt to .xy please?

Thx

Regards,

Corentin

Hello,

I am trying to 'fit' a curve (from a simulation) to a compressive test of a rubber. Using the LAW42 (Ogden formulation with 'mu and 'alpha').

I don't really understand how the 'request' and 'component' options work when I want to create a vector. As you can see in the attached screenshot.

And I don't have the 'tensile_test...' file as mentionned in the tutorial (in the picture) to check it. Thus, I can't figure it out how it works...

I just know that I need the Force and the displacement from the simulation, but with which type of file (.txt? .rad? etc...)

Can you help me please?

Thanks,

Regards.

Corentin

Once you able to run nominal run for Radioss solver it would generate T01,h3d result file which you can pull using File source or If you have access to latest 2017 /14.0 version you can use file assistant for same.
