AxialSp Material

.. function:: uniaxialMaterial('AxialSp', matTag,sce, fty, fcy, [bte, bty, bcy, fcr])
   :noindex:

   This command is used to construct a uniaxial AxialSp material object. This material model produces axial stress-strain curve of elastomeric bearings.



   ===================================   ===========================================================================
   ``matTag`` |int|                      integer tag identifying material
   ``sce`` |float|                       compressive modulus
   ``fty``    ``fcy`` |float|            yield stress under tension (   ``fty``) and compression (   ``fcy``) (see note 1)
   ``bte``  ``bty``  ``bcy`` |float|     reduction rate for tensile elastic range (   ``bte``), tensile yielding (   ``bty``) and compressive yielding (   ``bcy``) (see note 1)
   ``fcr`` |float|                       target point stress (see note 1)
