  • Phenomenon of fatigue: Obtain knowledge on the basics of fatigue and fracture of (welded, bolted and riveted) joints, including the aspects that are relevant and that are less relevant.
  • Designing for fatigue: basics of calculation using S-N curves, background of S-N curves, scatter in fatigue strength, importance of execution quality.
  • Fatigue loads in bridges: measurements of road traffic, measurements of rail traffic, determining which load effects are important, relationship with fatigue load models in standards.
  • Stress definition: when to use nominal stress, geometric stress and effective notch stress. How to extract the correct stresses from the finite element method.
  • Fatigue of orthotropic bridge decks: issues, remedies, repair and strengthening methods.
  • Remaining life after inspection: how to determine the remaining life and inspection intervals using fracture mechanics.
