fe-safe is the powerful and easy-to-use fatigue postprocessor for Abaqus, using proven techniques to accurately determine the fatigue life of metal components under complex cyclic loading. fe-safe combines finite element analysis results for multiple loading conditions from Abaqus with the cyclic load history to predict the life of the component.

fe-safe includes a database of cyclic material property data, and permits users to add their own property data from fatigue tests. fe-safe reads structural analysis data from, and writes results to, Abaqus output database (.odb) files and results (.fil) files.

More about fe-safe:

fe-safe Key Features:


  • Assemblies of different parts, surface finishes and materials can be analysed in a single run - fe-safe automatically changes the method of analysis as it moves from one material to another
  • Highly efficient coding plus parallel and distributed processing allow fe-safe to analyse large FE models and report results quickly


  • Advanced multiaxial algorithms are the core of fe-safe
  • Unique nodal elimination methods ensure no trade-off between speed and accuracy
  • Users consistently report excellent correlation with test results. Continuous development ensures fe-safe® maintains its position as the technology leader


  • fe-safe has many default settings and automatically selects the most appropriate algorithm based on the selected material
  • Standard analyses can be saved making it ideal for the non-specialist fatigue analyst
  • fe-safe is highly configurable for the advanced user
  • Direct interfaces to leading FEA suites such as Abaqus, ANSYS, I-deas, Nastran (MSC, NEi, NX) and Pro/Mechanica are driven from an intuitive, single screen, Windows-based GUI

With fe-safe as an integrated part of your design process, you have the ability to:

  • Optimise designs to use less material
  • Reduce product recalls and warranty costs
  • Optimise and validate design and test programmes
  • Improve correlation between test and analysis within a single user interface
  • Reduce prototype test times
  • Speed up analysis times, thereby reducing man-time hours
  • Increase confidence that your product designs pass their test schedules as “right first time”
