Abstract:

  • A probabilistic PoF‐based framework for fatigue life prediction is proposed.
  • A comprehensive procedure forquantifyingmultiple types of uncertaintyis presented.
  • The factors that contribute most to the resulting output uncertainty are identified.
  • The proposed frameworkdemonstrates high prediction accuracybyfull‐scale tests.
