First, organize the experiment data.

Convert true stress-true strain using nominal stress-nominal strain.

Then find the equivalent stress-equivalent strain relation for the LS-DYNA model.

Finally, using DEFINE_TABLE, considering the data of each strain rate.

Check the example file, please.

Thank you Akita-san for the information. I will go through it and try to implement it.

Dear Claudio Pedrazzi

Do you have any suggestions for this query? Thanks in advance.

Reika Akita Thank you once again for your response. I have a query, for the strain-rates for which the experiment was not carried out how do I extrapolate the values and predict the change in strength with intermediate strain rate?

Thanks in advance.
