Slope m1 and m2

Hello there,

While studying the theory behind mlife, I realized that I can only use one slope to determine DEL. I want to study the DEL in a tower after 20 years. This means that the DEL will be more likely below slope 2. Is Mlife able to understand both slopes and what is the right choice to choose m for the tower in this case?

Best regards,

Dear @Hussam.Al.Halabi,

MLife does not currently support a segmented S-N curve. MLife does support calculation of fatigue based on multiple Whöler exponents (m) if you want to see the sensitivity of fatigue to different values.

Best regards,
