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
|
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.
