Hi guys, assuming that your geometry, forces, and supports
are compatible with the limitations of COSMOSXpress, you can
utilize these stresses to perform manual fatigue calculations on
specific locations using Modified Goodman or the mean stress
correction method of your choice. Shigley "Mechanical Engineering
Design" or Collins "Failure of Materials in Mechanical Design" are
good references for this. Also try www.fatiguecalculator.com.
If you models don't really fit within the limitations of
COSMOSXpress (& surprisingly few do) then the stresses
calculated will not be of sufficient quality to bother doing a
fatigue calculation on. Not only can you determine stresses in more
diverse geometries or loading conditions in COSMOSWorks but the
Fatigue solver in COSMOSWorks Professional can combine multiple
loads, esitmate multi-directional effects, and provide Factor of
Safety plots for the whole system, not just for the individual
locations possible in a manual calculation.
You pretty much need to decide which is appropriate for your
engineering challenges.
Good luck!
