This command is used to construct a Dodd-Restrepo steel material

uniaxialMaterial Dodd_Restrepo $tag $Fy $Fsu $ESH $ESU $Youngs $ESHI $FSHI <$OmegaFac>

Note: Stresses and strains are defined engineering terms, as they are reported in a tensile test

$matTag	Integer tag identifying material
$Fy	Yield strength
$Fsu	Ultimate tensile strength (UTS)
$ESH	Tensile strain at initiation of strain hardening
$ESU	Tensile strain at the UTS
$Youngs	Modulus of elasticity
$ESHI	Tensile strain for a point on strain hardening curve, recommended range of values for ESHI: [ (ESU + 5ESH)/6, (ESU + 3ESH)/4]
$FSHI	Tensile stress at point on strain hardening curve corresponding to ESHI
$OmegaFac	Bauschinger curve roundness factor. Range: [0.75, 1.15]. Largest value tends to near a bilinear Bauschinger curve. Default = 1.0.

Examples:
