Calculate Ramberg Osgood equation alpha and N coefficients, and stress and strain.
The Ramberg Osgood equation alpha and N coefficients can be determined by
- calculating from the yield stress and strain and a second stress and strain data point (eg ultimate stress strain or any arbitrary data point).
- calculating from the yield stress and any two arbitrary stress strain data points
- calculating from the yield stress and one stress strain data point (alpha is assumed equal to 3/7)
- user defined alpha and N coefficients
The engineering stress, engineering strain, true stress and true strain can be calculated from either the user defined engineering stress or the user defined engineering strain.
