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

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 for engine components, exhaust systems, and brake discs
Crack propagation analysis with Paris law, Walker, and NASGRO models
Statistical fatigue analysis for 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.
