fe-safe

Durability Analysis Software for Finite Element Models.

What’s New in fe-safe 6.5

Highlights:

  • fe-safe licensing enhancements
  • Vibration fatigue
  • Theory of Critical Distances (TCD)
  • Distributed processing
  • Improved material management

Key Features

  • fe-safe material database provides fe-safe and safe4fatigue with a comprehensive database containing fatigue properties for commonly used materials.
  • Verity in fe-safe is a mesh-insensitive Structural Stress Method to predict failure locations and calculate fatigue lives for welded joints and structures.
  • fe-safe/TMF: Thermomechanical Fatigue (TMF) module provides fatigue life and design life analysis for structures subjected to fluctuating temperatures and stresses.
  • fe-safe/Rotate speeds up the fatigue analysis of rotating components by taking advantages of their axial symmetry.
  • fe-safe/TURBOlife assesses creep damage, fatigue damage and creep fatigue interactions.
Capabilities Summary:
  • Fatigue of welded joints
    • fe-safe includes the BS708 analysis as standard. With an exclusive license to the Verity Structural Stress Method, it brings new levels of accuracy to the analysis of structural welds, seam welds and spot welds.
  • Vibration fatigue
    • fe-safe uses steady state modal analysis, random transient analysis and power spectral density approach to analyze flexible components and structures with dynamic responses to applied loading.
  • Warranty curve
    • fe-safe combines variations in material fatigue strengths and variability in loading to calculate the probability of survival over a range of service lives.
  • Damage per block
    • By exporting fatigue damage for each “block” of loading, fe-safe shows clearly which parts of duty cycle are contributing the most fatigue damage for re-design purposes.
  • Manufacturing effects
    • fe-safe reads results of FEA of a forming or assembly process to estimate residual stresses for rapid sensitivity analysis.
  • Signal processing
    • Signal processing, load history manipulation, fatigue from strain gauges, and generation of accelerated testing signals are among the many features included as standard.
