  1. How to consider Fatigue load case in AutoPIPE?
    1. Method #1
    2. Method #2
    3. Method #3:
      • Using AutoPIPE 2025 and higher:
        • See AutoPIPE help> Results Interpretation> Fatigue Analysis (Non-ASME NB Models)
        • See AutoPIPE Help> General stress Calculations> Fatigue Evaluation Example
        • Webinar: "Critical Piping Lifecycle Insight with Fatigue Analysis in AutoPIPE Advanced" - click here
  2. Fatigue analysis with AutoPIPE Harmonic analysis command
  3. Reference / Equation used for fatigue analysis settings training
  4. Fatigue reported moments do not match static local moments, why?
    • Answer: 
    • Review "Apply modulus ratio" option. Decide if this setting should be enabled or disabled for your model analysis.
    • This options is mandatory for some Codes (ex. ASME BPVC III - NB).
