Arguments

$MaterialLabel
Unique Material Label for reference
$fY
Elastic Modulus
$MaterialDescription
Text. Optional, default = blank {}
$E
Elastic Modulus. Optional, default = 29,000 ksi
$Bsh
Strain-Hardening Ratio. Optional, default = 0.05 (5% hardening ratio)
$R0
Parameter to control the transition from elastic to plastic branches. Recommended value between 10 and 20. Optional, default = 18
$cR1
Parameter to control the transition from elastic to plastic branches. Recommended value ~0.925. Optional, default = 0.925
$cR2
Parameter to control the transition from elastic to plastic branches. Recommended value ~0.15. Optional, default = 0.15
$a1
Isotropic hardening parameter, increase of compression yield envelope as proportion of yield strength after a plastic strain of a2*(Fy/E). Optional, default = 0.
$a2
Isotropic hardening parameter, see a1. Optional, default = 1.
$a3
Isotropic hardening parameter, increase of tension yield envelope as proportion of yield strength after a plastic strain of a4*(Fy/E). Optional, default = 0.
$a4
Isotropic hardening parameter, see a3. Optional, default = 1.
$WeightDensity
Volumetric Weight Density of Material. Used to calculated section WeightDensity: sectionWeightDensity=$materialWeightDensity*SectionArea. Optional, default = 0.
NOT IMPLEMENTED IN CURRENT VERSION


Notes

The addMaterial command must be placed at the end of each Material-data definition, as it takes all data defined since the last addMaterial command and define the Material.


Options

OpenSees Object

This MaterialModel is based on the OpenSees Steel02 Material -- Giuffré-Menegotto-Pinto Model with Isotropic Strain Hardening
