This command is used to construct a uniaxial J2 Plasticity material object with isotropic and kinematic hardening.

uniaxialMaterial UniaxialJ2Plasticity $matTag $E $sigmaY $Hkin $Hiso

---

$matTag	unique material object integer tag
$E	initial tangent stiffness
$sigmaY	yield stress (or force)
$Hkin	kinematic hardening Modulus
$Hiso	isotropic hardening Modulus

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