fe-safe
Predict fatigue and durability with industry-leading FEA-based analysis.
fe-safe Overview
fe-safe is a durability analysis software suite for finite element models. Since the early 1990s it has set the benchmark for FEA-based fatigue analysis. fe-safe calculates fatigue lives at every node of a model, producing contour plots that reveal fatigue life and crack initiation sites - so critical hotspots are never missed. It performs strain- and stress-based calculations and applies advanced critical-plane multiaxial fatigue with built-in plasticity modelling to post-process results from a single elastic FEA run.
Abaqus Extended Portfolio
Interface tokens
An Abaqus interface token (Abaqus/CAE, the graphical user interface) also runs the fe-safe, Isight and Tosca interfaces, without additional purchase.

SimUnit solver tokens
The same solver tokens run every SIMULIA solver and the simulation apps on the 3DEXPERIENCE® platform. They are checked out while a job runs, and checked back in when it ends.

Frequently Asked Questions
Which FEA solvers does fe-safe support?
fe-safe interfaces directly with Abaqus, ANSYS, Nastran (MSC, NEi, NX) and Pro/Mechanica. Results files are read natively, with no manual data conversion.
Can fe-safe analyse welded structures?
Yes. The patented Verity Structural Stress Method handles seam, structural and spot-welded joints, providing mesh-insensitive fatigue life validated against more than 3,500 physical tests.
How does fe-safe handle high-temperature and creep fatigue?
fe-safe/TURBOlife performs high-temperature fatigue with creep and creep-fatigue interaction, while fe-safe/TMF adds time-dependent thermo-mechanical fatigue mechanisms to the core solver.
How can I buy fe-safe?
