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
