plug-in "JC constants"

Hi all,

I'm looking for a plug-in I had used a couple of years ago. It was called "JC constants plug-in". It calibrated the parameters of a Johnson-Cook elastic-plastic material model based on a basic characteristic from a datasheet (E-modulus, Rp02, Yield stress, A%, stress at break). Very simple to use. I can't find it in any of the plug-in pages (QA00000008694 or post4006). Does anyone have this plug-in and could share it, or know where to find it?

Thank you,

Jimmy
