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.
