Wahl Correction Factor
Wahl correction factor, abbreviated as K, also called Wahl stress factor or spring stress correction factor, is a method to find out the effect of direct sheat and change in coil curvature in a spring.
Wahl correction factor formula
\(\large{ K = \frac{ 4\;C \;-\; 1 }{ 4\;C \;-\; 4 } + \frac{ 0.615 }{ C } }\) |
Where:
\(\large{ K }\) = stress correction factor
\(\large{ C }\) = spring index
