This command is used to construct a bilin something or other
uniaxialMaterial Bilin $matTag $Fy $E0 $b <$a1 $a2 $a3 $a4> |
$matTag | integer tag identifying material |
$Fy | yield strength |
$E0 | initial elastic tangent |
$b | strain-hardening ratio (ratio between post-yield tangent and initial elastic tangent) |
$a1 | isotropic hardening parameter, increase of compression yield envelope as proportion of yield strength after a plastic strain of $a2*($Fy/E0). (optional) |
$a2 | isotropic hardening parameter (see explanation under $a1). (optional). |
$a3 | isotropic hardening parameter, increase of tension yield envelope as proportion of yield strength after a plastic strain of $a4*($Fy/E0). (optional) |
$a4 | isotropic hardening parameter (see explanation under $a3). (optional) |
