A parabolic curve joining 'S_e' on the stress amplitude axis and '$S_{ut}$' on the mean stress axis is called the Gerber parabola.
According to the Gerber criteria, the region below this curve is considered to be safe. The equation for the Gerber parabolic curve is,
$(\frac{S_m}{S_{ut}})^2$ + $(\frac{S_a}{S_{e}})$ = …
