| $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) |
