Background information on Fatigue analysis in SimSolid.
Fatigue Assessment Methods
In SimSolid, uniaxial and multiaxial fatigue analysis using SN (stress-life) and EN (strain-life) approach is supported.
Stress-life (SN) Approach
The stress-life method works well in predicting fatigue life when the stress level in the structure falls mostly in the elastic range.
Strain-life (EN) Approach
The EN Approach uses plastic-elastic strain results to perform strain-life analysis.
