EQUATIONS TO FIND YOUNGS MODULUS,CONCRETE DAMAGE PLASTICITY PARAMETERS FOR STEEL FIBRE REINFORCED CONCRETE

[Shreyas M]

I am in need of equations to find youngs modulus,CDPM parameters of steel fibre reinforced concrete for non linear analysis in abaqus.I have experimental test results of tensile stress and strain and vary volume fraction of SFRC(from double punch test).
Please do help me in finding solution.

Modulus is just the slope of the stress-strain curve.
No idea what CPDM is.
