Loadings

fe-safe can predict fatigue lives from a range of loading types.

SIMULIA fe-safe - Loading Possibilies
=

Use many loading types

  • Single load time history applied to a linear elastic Finite Element model
  • Multiple time histories of loading superimposed in fe-safe (more than 4000 load histories can be applied)
  • Sequence of FEA stresses (elastic or elastic-plastic, linear or non-linear)
  • Superimposition of steady state modal solutions
  • Superimposition of transient dynamic modal solutions
  • PSD loading, block loading test programmes, rainflow cycle matrices
  • Effects of forming or assembly stresses can be included
  • Combine different types of loadings

Output to FEA

A wide range of results in a single run.

=

Multiple output possibilities

  • Contours of fatigue life show crack initiation site
  • Contours of stress-based factors of strength for a specified design life
  • Probability of survival for specified lives (the ‘warrantycurve’)
  • Which loads need to be included in a test program
  • Contour plots of maximum stress during loading
  • Detailed results – time histories of stresses and strain, Haigh and Smith diagrams, Dang Van plots and many more
  • Damage at the critical location from each loading block
  • Vector plots identifying critical damage planes
