This command is used to construct a Ramberg–Osgood steel material object.
| uniaxialMaterial RambergOsgoodSteel $matTag $fy $Es $a $n |
| $matTag | integer tag identifying material |
| $fy | yield strength |
| $E0 | initial elastic tangent |
| $a | “yield offset” and the Commonly used value for $a is 0.002 |
| $n | Parameters to control the transition from elastic to plastic branches. And controls the hardening of the material by increasing the "n" hardening ratio will be decreased.
