This command is used to construct an elastic bilinear uniaxial material object. Unlike all other bilinear materials, the unloading curve follows the loading curve exactly.
| uniaxialMaterial ElasticBilin $matTag $EP1 $EP2 $epsP2 <$EN1 $EN2 $epsN2> |
| $matTag | integer tag identifying material | |
| $EP1 | tangent in tension for stains: 0 <= strains <= $epsP2 | |
| $EP2 | tangent when material in tension with strains > $epsP2 | |
| $epsP2 | strain at which material changes tangent in tension. | |
| $EN1 | optional, default = $EP1. tangent in compression for stains: 0 < strains <= $epsN2 | |
| $EN2 | optional, default = $EP2. tangent in compression with strains < $epsN2 | |
| $epsN2 | optional, default = -epsP2. strain at which material changes tangent in compression. |
NOTE:
eps0 can not be controlled. It is always zero.
