This command is used to construct a Ramberg–Osgood steel material object.

uniaxialMaterial RambergOsgoodSteel $matTag $fy $Es $a $n

Commonly used values for $n are ~5 or greater. ($n must be odd number).


$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.
