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.|
eps0 can not be controlled. It is always zero.
