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.
