addMaterial

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.

OpenSees Object

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