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)

$f2

Stress/Force value in second envelope point. Optional, default = 1.3*$fY

$f3

Stress/Force value in third envelope point. Optional, default = 1.35*$fY

$eps3

Strain/Deformation value in third envelope point. Optional, default = 1.0

$pinchX

Pinching factor for strain (or deformation) during reloading. Optional, default = 1.

$pinchY

Pinching factor for stress (or force) during reloading. Optional, default = 1.

$damage1

Damage due to ductility: D1(mu-1). Optional, default = 0.

$damage2

Damage due to energy: D2(Eii/Eult). Optional, default = 0.

$beta

Power used to determine the degraded unloading stiffness based on ductility, mu^(-beta). Optional, default = 0.5

$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 Hysteretic Material
