Simsolid stress strain curve

KF_001

Which the nominal or true stress/strain should I input for the stress vs strain curve to do non-linear structural analysis in Simsolid?

I searched on Google, but I cannot find it. I'd appreciate if you could help me in this question.

Hello,

By default, Simsolid assumes the input curve is engineering/nominal stress-strain in the non-linear structural analysis. However, if you have a true stress-strain curve, use the following to convert true stress-strain curve to engineering stress-strain curve.

CSV File Format

CSV Fields

The format of the file has a header "strain, stress" and corresponding row of values. If the data is true stress-strain, add [true] to the end of the header row:

stress, strain, [true]

Thanks,

Thank you very much for your reply. I have nominal stress-strain curve, so I understand I can use it as is. I appreciate your quick reply!
