uniaxialMaterial('Dodd_Restrepo', matTag, Fy, Fsu, ESH, ESU, Youngs, ESHI, FSHI, OmegaFac=1.0)
This command is used to construct a Dodd-Restrepo steel material
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 |
|
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 |
|
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. |
