You can use Multi-loadcases to run multiple linear structural analyses with common constraints. Linear structural
analysis assumes the model is loaded slowly (static) and stresses do not exceed the yield strength of any part material
(linear).
Background information on Fatigue analysis in SimSolid.
Fatigue Assessment Methods
In SimSolid, uniaxial and multiaxial fatigue analysis using S-N (stress-life) and E-N (strain-life) approach is supported.
Stress-life (S-N) 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 (E-N) Approach
The E-N Approach uses plastic-elastic strain results to perform strain-life analysis.
Rainflow Cycle Counting
Use cycle counting to extract discrete simple "equivalent" constant amplitude cycles from a random loading sequence.
Mean Stress Correction
Use mean stress correction to account for the effect of non-zero mean stresses.
