Efficient Durability Analysis with safe4fatigue

safe4fatigue is an integrated system for managing durability analysis. It provides advanced multiaxial fatigue and durability analysis from measured or simulated strain signals, peak-valley files, cycle histograms and PSDs.

fe-safe includes safe4fatigue module at no added cost. It provides all the capabilities needed to analyze practical durability applications without the overhead of complex ‘management' systems. Its attractive, easy-to-use user interface provides fast access to complex analysis procedures. You can automate repetitive tasks using powerful macro-recording and batch processing.

Regardless of the complexity of your fatigue analysis, safe4fatigue fits smoothly into your design process, enabling you to develop durable products.

At a Glance

safe4fatigue is an integrated system for managing durability analysis. It is ideal for the user who wants to conduct durability analyses from measured or simulated strain signals without the overhead of a complex ‘management' system. Results are displayed in the form of:

  • Cycle and damage histograms
  • Cycle and damage density diagrams
  • Stress-strain hysteresis loops or plots of fatigue damage to show the most damaging portions of a signal.

safe4fatigue incorporates a powerful signal processing package, including modules for amplitude analysis, frequency analysis and digital filtering. It includes multi-channel peak-valley with cycle omission, lots of signal manipulation functions, rainflow, level crossing, time-at-level and frequency domain analysis (PSD, transfer functions).

safe4fatigue interfaces to many common data acquisition systems and data structures.

  • Analyze strain gauge data and service loading using an intuitive and user-friendly GUI.
  • Improve correlation between test and analysis within a single user interface.
  • Optimize durability test programs to be faster and more realistic.
  • Enables fatigue from measured or simulated strain signals without the overhead of a complex ‘management' system.

Capabilities & Typical Applications

  • Provides advanced multiaxial fatigue and durability analysis, from measured or simulated strain signals, peak-valley files and cycle histograms.
  • Incorporates a powerful signal processing package.
  • Interfaces to many common data acquisition systems and data structures.
  • Includes an extensive material database and comprehensive material data handling functions.
  • Optimized for use on all Windows platforms, UNIX and Linux.
  • Easy to use Explorer-style tree view of active data files, data channels and results.
  • Flexible graphical display, including stacked and overlaid plots, 3D histograms and contour plots.
  • Drag-and-drop data files from other applications.
  • Exports to Microsoft Office and other applications.
  • Optimized to handle large data sets quickly and efficiently.
  • Models gray cast iron using an incremental damage procedure.
  • Advanced multiaxial fatigue software provides principal strain and Brown-Miller critical plane analysis with mean stress corrections, from complex strain-time histories from strain gauge rosettes.
  • Analyzes several signals in a single run, with the results output to a table.
  • Shares GUI as fe-safe and integrates to create a single user interface for test engineers and fatigue analysts.
  • Generates and exports test command signals containing only the damaging parts of a load history exported to a test rig.
  • Optimizes test drive signals to ensure efficient use of test equipment.

Typical Applications

  • Civil engineering structure monitoring
  • Automotive and aerospace component validation
  • 'Road load' data analysis
  • Strain gauge data analysis
  • Accelerated prototype testing
