...... Table 6: Part of the decision table

Basquin equation is as follows:

= m S N C (13) where m and C are the coefficients determined by different materials. Then by taking the logarithm of both sides of this equation and get: + = lg lg lg N m S C (14)

The S-N curve based on Eq. SS Range as shown below.
