This command is used to construct a uniaxial multilinear material object.
| uniaxialMaterial MultiLinear $matTag $u1 $f1 $u2 $f2 $u3 $f3 $u4 $f4 $u5 $f5 |
| $matTag | integer tag identifying material |
| $u1 | yield strength |
| $f1 | initial elastic tangent |
| $u2 | strain-hardening ratio (ratio between post-yield tangent and initial elastic tangent) |
| $f2 | isotropic hardening parameter, increase of compression yield envelope as proportion of yield strength after a plastic strain of $a2*($Fy/E0). (optional) |
| $u3 | isotropic hardening parameter (see explanation under $a1). (optional). |
| $f3 | isotropic hardening parameter, increase of tension yield envelope as proportion of yield strength after a plastic strain of $a4*($Fy/E0). (optional) |
| $u4 | isotropic hardening parameter (see explanation under $a3). (optional) |
