SteelMP

This command is used to construct a uniaxial Menegotto-Pinto steel material object.

uniaxialMaterial SteelMP $matTag $sigmaY $E
        $b

matTag

unique material object integer tag

sigmaY

yield stress or force

E

initial tangent stiffness

b

strain-hardening ratio (ratio between post-yield tangent and initial elastic tangent)

Note: For this material class, the sensitivity parameters can be: sigmaY, E, b
