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
(int)integer tag identifying material Fy
(float)Yield strength Fsu
(float)Ultimate tensile strength (UTS) ESH
(float)Tensile strain at initiation of strain hardening ESU
(float)Tensile strain at the UTS Youngs
(float)Modulus of elasticity ESHI
(float)Tensile strain for a point on strain hardening curve, recommended range of values for ESHI: [ (ESU + 5*ESH)/6, (ESU + 3*ESH)/4] FSHI
(float)Tensile stress at point on strain hardening curve corresponding to ESHI OmegaFac
(float)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.
