Does anyone has references referring to the Ramberg Osgood nonlinear moment curvature relationship?

Thanks..

RE: Ramberg Osgood

We have run into ramberg & osgood at my job while dealing with stresses and strain in during pipelaying but we kind of put that on the back burner for now.

(OP)
Anyone know the A and B coefficient for the nonlinear moment curvature Ramberg osgood coeff especially for X65 grade pipline?

Thanks

RE: Ramberg Osgood

The original article by Ramberg & Osgood "Stress-Strain Curve by Three Parameters" can be downloaded from NACA.

Google: NACA TN-902 1943

Go to the first web site and enter: TN-902

You will see the title and can download the pdf file.
