      Hello everyone,



      • What is the basic difference between Stress life and Strain life?

      • When can I utilize the strain life method in fatigue analysis?


      Thanking you in anticipation.

      Hi,


      HCF : Stresses in your simulation less than Yield Strength. This is due to stress driven 


      LCF: Stresses in your simulation more than Yield Strength. This is due to strain driven 


      In LCF need to be consider Neuber correction criteria for elastic plastic strain correlation.
