4.14.5.35. Backbone Material¶
- uniaxialMaterial('Backbone', matTag, backboneTag)
This command uses a Hysteretic Backbone object to represent a path-independent uniaxial material. Since it is path-independent, no state information is stored by BackboneMaterial.
matTag
(int)integer tag identifying material
backboneTag
(int)integer tag identifying a predefined backbone function.
