About FEMFAT
FEMFAT is a globally recognized fatigue life prediction and durability analysis software developed by Magna Engineering Center Steyr, now part of the Siemens Digital Industries Software portfolio. With over 30 years of continuous development, it is trusted by automotive OEMs, aerospace manufacturers, and industrial machinery companies for accurate fatigue assessment under complex loading conditions.
Core Analysis Capabilities
| Capability | Details |
|---|---|
| Multi-axial fatigue analysis | Using Findley, Dang Van, Crossland, and Sines critical plane methods |
| Stress-life (S-N) | And strain-life (E-N) approaches with mean stress correction (Goodman, Gerber, Morrow, Smith-Watson-Topper) |
| Welded joint fatigue assessment | Per Eurocode 3, IIW recommendations, FKM guidelines, and AWS D1.1 |
| Vibration fatigue | And frequency-domain analysis for random loading with PSD input |
| Thermomechanical fatigue | Engine components, exhaust systems, and brake discs |
| Crack propagation | Analysis with Paris law, Walker, and NASGRO models |
| Statistical fatigue analysis | Scatter assessment and reliability-based design |
FEA Solver Integration
Direct result import from ANSYS, Abaqus, NASTRAN, OptiStruct, PERMAS, CalculiX, and other major solvers via neutral formats (OP2, DAT, RST, FIL, UNV) and direct database connections.
Who It's For
- Durability engineers assessing fatigue life of components
- Automotive OEM and supplier CAE teams
- Aerospace and machinery engineers analyzing welds and joints
- Analysts importing results from ANSYS, Abaqus, NASTRAN, and OptiStruct
Why Professionals Choose FEMFAT
FEMFAT is the reference for fatigue life prediction — 30+ years of validated methods for multi-axial, welded-joint, vibration, and thermomechanical fatigue backed by Magna's testing data. It reads results from every major FEA solver, so it slots into any existing simulation workflow.
