Fatigue Software


We have developed our own Fatigue Software which can be tailored to your requirements. We can supply FEMAP with NXNastran.

Analysis by Firth have developed cost effective software which will process strain gauge data and determine fatigue life. This program performs the following functions:-

  • Read in strain gauge data in various formats (e.g. SDRC I-DEAS, nCode, plain text file)
  • Convert data to reversals
  • Convert strain to stresses (allowance for offset & SCF)
  • Perform rainflow count to ASTME-1047
  • Apply the Goodman Correction where appropriate
  • Determine fatigue damage

Three versions of the software are now available, the first based on a known S-N curve, the second based on the weld classes in BS7608/BS5400 Part 10 and a third which only carries out the rainflow count. All version are capable of processing 1 million data points. The software can also be tailored to your specific requirements. It is available for lease or purchase.

Other engineering software packages available include :-

  • Standard section properties calculator

  • Complex section properties calculator (thin walled sections)

  • Bolt Groups - calculate the forces in a loaded bolt group
