This command is used to construct an ElasticIsotropic material object.

nDMaterial ElasticIsotropic $matTag $E $v <$rho>

---

$matTag	integer tag identifying material
$E	elastic Modulus
$v	Poisson's ratio
$rho	mass desnsity

The material formulations for the ElasticIsotropic object are "ThreeDimensional," "PlaneStrain," "Plane Stress," "AxiSymmetric," and "PlateFiber."
