DoddRestrepo
This command is used to construct a Dodd-Restrepo steel material
Model.uniaxial(“Dodd_Restrepo”, name, fy, fu, esh, esu, E, eshi, fshi)
| fy |
float
|
Yield stress. |
| fu |
float
|
Ultimate tensile strength (UTS) |
| esh |
float
|
Tensile strain at initiation of strain hardening |
| esu |
float
|
Tensile strain at the UTS |
| E |
float
|
Young’s modulus of elasticity |
| eshi |
float
|
Tensile strain for a point on strain hardening curve, recommended range of values for eshI: \(\left[ \frac{\texttt{esu} 5 \texttt{esh}}{6}, \frac{\texttt{esu} 3 \texttt{esh}}{4}\right]\) |
| fshi |
float
|
Tensile stress at point on strain hardening curve corresponding to eshI |
| OmegaFac = 1.0 |
float
|
Roundedness factor for Bauschinger curve in cycle reversals from the strain hardening curve. Range: \(\left[0.75, 1.15\right]\). 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.
