What is FEMFAT?

FEMFAT offers fatigue life prediction (FLP) of all vehicle components (engine, gearbox, chassis, frames, car bodies and structures) and machinery equipment based on Finite Element Analyses (FEA). Additionally to consideration of complex multi-axial loadings an assessment of welding seams as well as spot welds and self piercing rivets in steel and aluminium can be carried out. Components undergoing thermo-mechanical loadings can be assessed considering effects of material plasticity, elevated temperature (oxidation) and creep.

Key Features & Benefits

  • Reliable results on the fatigue life of structures to improve critical points
  • Virtual optimization results in less weight, higher level prototypes which consequently leads to less tests
  • Multiple fatigue influences (notch, mean stress, manufacturing technology,…)
  • Large range of interfaces to finite element codes
  • Material data based on FKM guidelines
  • Analyses results verified by countless tests in own test lab
  • Leading fatigue analysis code in automotive industry
  • Large basis of internal usage-
  • Technical leadership in many areas (e.g. 3D-stresses, joints, production influences)
  • High analysis speed and flexibility
  • Open database concepts (material, joints)
  • Easy handling: minimum of settings and methods required
  • Best verifications and blind benchmark results


FE-based software for fatigue analysis and optimization on components like
  • Engine crank case, cylinder head, crank shaft, and connecting rod
  • Axles and suspension components
  • Body in white, chassis structures with spot joints
  • Transmission housing and transmission components
  • Welded steel and aluminium structures
  • Low weight frames for tractors, trucks, busses, rail transport systems, cranes, etc.
