Tangent Modulus for ASTM A36 and A992

VMHVMH
Hi, I was wondering what others are using for the tangent modulus for ASTM A36 and A992 materials? Thanks

    Have seen some people computing the tangent modulus as:

    (Ultimate Stress - Yield Stress) / (Ultimate Strain - Yield Strain)

    But I preffer to enter directly the engineering stress strain data points as a table using the *PLASTIC card and CCX custom values. @Victor , will be possible to do this in the GUI directly?

    Edited a typo on the formula.

    Sergio,

    What values do you use for the table?
    Thanks

    Those from actual testing. Sometimes I "redraw" the curve but rescaling the shape to get the minimun expected values for the material grade, but keeping the shape of the curve. And must be converted to real values and not engineering stress/strain.

    I found these General Nonlinear Material from Ansys...
