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.
