Industry is putting increasing pressure on manufacturers to use less material to deliver lightweight but stronger components, lower warranty and recall costs and all in less time. Many companies use advanced finite element analysis to calculate design stresses, but the fatigue analysis is often still done by manually picking stress points for spreadsheet analysis. This is time-consuming and unreliable because it is easy to miss failure locations.


fe-safe was the first commercially available fatigue analysis software to focus on modern multiaxial strain-based fatigue methods and it continues to set the benchmark for fatigue analysis software.
