3. Fatigue calculations (simple tensile loads)

3.1 Main parameters influencing fatigue behavior

SCROLL TO TOP

3.1.1 Metallurgical parameters

  • Grain size

    Fine-grained structures have a better fatigue life than coarse-grained structures.

  • Fibre orientation in relation to load direction

    The general orientation of the grains (fibering) gives the material a more or less pronounced anisotropy. Static properties and fatigue life are better in the long...
