Plastic Modulus
(OP)
What would you say is a generally accepted value for the plastic modulus of structural steel (A36 or A992)? The elastic is 29,000 ksi......but I am having a difficult time finding an agreed upon value for Ep .

What type of structure are you looking at ?
We're not looking at plastic bending, right?

the angles of the curve are: atan(E) and atan (E/10000).

Ramberg-Osgood parameters are a way of modelling the elastic-plastic material curve.

RE: Plastic Modulus
@rb1957: Yes......or more accurately: how much compression is it seeing prior to buckling?
RE: Plastic Modulus
I made a mistake on my previous post. It should be atan(E/10000).

RE: Plastic Modulus
Are you sure it wasn't right the first time? I found that code on-line, and the atan(E/100) value is for a material with a work hardening range (like steel).
