This command is used to construct a Dodd-Restrepo steel material
| uniaxialMaterial Dodd_Restrepo $tag $Fy $Fsu $ESH $ESU $Youngs $ESHI $FSHI <$OmegaFac> |
| $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 + 5*ESH)/6, (ESU + 3*ESH)/4] |
| $FSHI | Tensile stress at point on strain hardening curve corresponding to ESHI |
| $OmegaFac | Roundedness factor for Bauschinger curve in cycle reversals from the strain hardening curve. Range: [0.75, 1.15]. Largest value tends to near a bilinear Bauschinger curve. Default = 1.0. |
Note: Stresses and strains are defined in engineering terms, as they are reported in a tensile test.
