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.
Options
OpenSees Object
This MaterialModel is based on the OpenSees Hysteretic Material
