Arguments

$MaterialLabel
Unique Material Label for reference
$eps1
strain/deformation at first point in curve
$f1
stress/force at first point in curve
$eps2
strain/deformation at second point in curve
$f2
stress/force at first second in curve
$eps3
strain/deformation at third point in curve
$f3
stress/force at first third in curve
$MaterialDescription
Text. Optional, default = blank {}
$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.
