Ramberg-Osgood relationship
Encyclopedia : R : RA : RAM : Ramberg-Osgood relationship
The Ramberg-Osgood equation was created to describe the relationship between stress and strain—that is, the stress-strain curve—in materials near their yield points. It says that
[\epsilon = \frac + K(\frac)^n],Ramberg, W., & Osgood, W. R. (1943). Description of stress-strain curves by three parameters. Technical Note No. 902, National Advisory Committee For Aeronautics, Washington DC. [link]
where
- [\epsilon] is strain,
- [\sigma] is stress,
- [E] is Young's modulus, and
- [K] and [n] are constants that depend on the material being considered.
