Functionalities SIMULIA fe-safe
Powerful features to perform your accurate fatigue analysis
fe-safe includes a wide range of analysis methods, all of which are included in the standard package.
Use many analysis methods
- Strain-based multiaxial fatigue algorithms—axial strain, shear strain, Brown-Miller with a multiaxial Neuber’s ruleand cyclic plasticity model
- S-N curve analysis including multiaxial fatigue using axial stress or a new Brown-Miller analysis formulated for use with S-N curves
- Dang Van multiaxial fatigue for high cycle design
- Plots of material data including the effect of temperature,strain rate etc.
- Advanced analysis methods for fatigue of cast irons
- Analysis of welded joints
- High temperature fatigue
- Analysis from elastic and elastic-plastic FEA stresses, linear and non-linear analysis
- Automatic detection of surfaces
- Automatic detection of fatigue hot-spots
- Comprehensive element/node group management
- Stress gradient corrections
- Critical distance algorithms
- Critical plane methods for random vibration fatigue
- Analysis of rotating parts
fe-safe can predict fatigue lives from a range of loading types.
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
