Finite Element for High Cycle Fatigue
Finite Element for High Cycle Fatigue
(OP)
I am looking for a finite element package to model high cycle fatigue failure. Are there any free packages available and if so, which are recommended?
Thanks.

unfortunately, all the fatigue add-ons I know are not freeware. Even the CosmosWorks' module Corus refers to is not free. The same is for Ansys Workbench Fatigue feature. Moreover, all these work inside programs which are very expensive by nature...
However, provided that the free FE code you want to use is able to perform results' combinations (i.e. linear combinations of loadcases), you can do high-cycle fatigue assessment "by yourself", IMO without paying the price for any more software.

Does your "widget" have any of these features?

TGS4 - our widget does not have these features - it is a simple shaft with a filleted shoulder subject to rotational low and high cycle fatigue. It is believed that the shaft is in elastic bending hence is not rotating concentrically - leading to the high cycle fatigue.
MechEng2005 - Yes, I agree. This will be achievable for both the fatigue AND nominal stress calculations.
