Other Methods for Fitting a Curve
The following methods require certain parameters other than UTS to define the SN/EN curve.
- From the Assign Material dialog, click the My Material tab and select your created material.
- For Number of SN curves, select Single.
- For Curve Type, select Ratio/ Haigh Diagram.
- Select an input method.
