Durability & Fatigue
fe-safe
The technical leader in fatigue analysis for finite element models. Multiaxial strain-based, rubber, and welded-joint fatigue — built on three decades of close collaboration with industry.
Overview
Stop Hand-Picking Fatigue Hotspots
Many companies still rely on manual stress-point selection for spreadsheet fatigue calculations — slow, error-prone, and prone to missing critical failure sites. fe-safe automates fatigue assessment across every node, every load case, every duty cycle.
Direct interfaces with Abaqus, ANSYS, and Nastran mean fe-safe drops into your existing FEA workflow — no remeshing, no rebuilding, just better fatigue answers.
fe-safe At a Glance
What fe-safe Delivers
Whole-Model Fatigue Lives
Calculates fatigue lives at every point on the model — contour plots reveal lives and crack sites without missing critical locations.
Lightweighting Insight
Highlights where the component is under strength and where there are opportunities to save material and weight.
Warranty & Probability
Estimates warranty claim curves based on probabilities of failure.
Duty-Cycle Damage
Identifies which parts of a duty cycle are most damaging — supporting shorter, smarter prototype testing.
Manufacturing Effects
Accounts for residual stresses from stamping/forming, surface finishes, and material variation in castings/forgings.
Random Vibration Fatigue
Fast frequency-domain fatigue from single/multi-channel PSDs/CSDs with multi-axial critical plane analysis.
