uniaxialMaterial commands

Several uniaxial materials are available for DDM-based FE response sensitivity computation.

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

$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).

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