Fatigue in LS-Dyna

      Hi all.

      I'm simulating drilling in LS-Dyna. 

      I've now reached the wear and tear stage. I want to calculate wear using the classical method, using the SN curve.

      I have a dilemma about which method to choose. This will be one of three:

      1.SN curve + FATIGUE card

      2.SN curve + FREQUENCY_DOMAIN_RANDOM_VIBRATION_FATIGUE card

      3.SN curve + FATIGUE_MULTIAXIAL card.

      Thank you.

      It depends on what type of loading you have: deterministic unaxial, random vibration, or multiaxial loading, and you would be the best judge of that.

        Yes, but I need advice. I have submission and appeal.
