4.14.1.6. RambergOsgoodSteel

uniaxialMaterial('RambergOsgoodSteel', matTag, fy, E0, a, n)

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

matTag (int)	integer tag identifying material
fy (float)	Yield strength
E0 (float)	initial elastic tangent
a (float)	“yield offset” and the Commonly used value for a is 0.002
n (float)	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. Commonly used values for n are ~5 or greater.
