FEMFAT utilizes the cutting plane method in combination with considering the impact from casting, production and machining processes. FEMFAT basic is used with proportional loads and simple load spectra.

The methods used in FEMFAT are based on

  • the latest scientific findings of the German FKM guideline,
  • the work of Huck/Thrainer/Schutz (synthetic S/N curves),
  • the local stress-strain model (TU-Darmstadt)

In addition to this, methods applicable to FEM were developed, such as computing the notch influence in terms of the relative stress gradient or consideration of the interaction of different stress tensors by using the `critical cutting plane´ method. All these hypothesis have been checked by comparing numerous test series with fatigue analysis results and have been verified during many years of practical use.
combines know-how from special fields such as

  • the finite element method,
  • characterization of material properties and
  • fatigue testing.
