AxialSpHD

This command is used to construct a uniaxial AxialSpHD material object. This material model produces axial stress-strain curve of elastomeric bearings including hardening behavior.

uniaxialMaterial AxialSpHD $matTag $sce $fty $fcy
        <$bte $bty $bth $bcy $fcr $ath>

matTag

integer tag identifying material

sce

compressive modulus

fty fcy

yield stress under tension (fty) and compression (fcy) (see note 1)

bte bty bth bcy

reduction rate for tensile elastic range (bte), tensile yielding (bty), tensile hardening (bth) and compressive yielding (bcy) (see note 1)

fcr

target point stress (see note 1)

ath

hardening strain ratio to yield strain (see note 1)

NOTES:

  1. Input parameters are required to satisfy followings.

    fcy < 0.0 < fty

    0.0 <= bty < bth < bte <= 1.0

    0.0 <= bcy <= 1.0

    fcy <= fcr <= 0.0

    1.0 <= ath
