This command is used to construct a UniaxialMaterial object which represents uniaxial stress-strain (or force-deformation) relationships.

uniaxialMaterial matType? matTag? arg1? ...

---

The type of material created and the additional arguments required depends on the matType? provided in the command.

NOTE:

The valid queries to any uniaxial material when creating an ElementRecorder are 'strain,' 'stress,' and 'tangent.' Some materials have additional queries to which they will respond. These are documented in the NOTES section for those materials.

The following contain information about matType? and the args required for each of the available material types:
