FEA fatigue
FEA fatigue
(OP)
Hi,
Which program performs fatigue analyses by FEM, both elastic and elasto-plastic domain? I am interested in thermo-mechanical fatigue.
Thank you!

adding to JohnHors:
- Fatigue add-ons of commercial FEA programs performs automatically post-processings you can perform yourself "by hand" (well, at least with Excel...)
- without having a Fatigue add-on, you can proceed like this:
1- a) run a solution for every loadcase which composes your load history, or b) run a transient analysis in which you save the result data for every time step
2- for every loadcase, have your program list the nodal or element stress values you are interested in
3- import the data in Excel (if you have more than 65000 nodes, split the results files)
4- set up in Excel the Voeller or Design Fatigue curve, the Haigh correction, etc, as needed
5- calculate the cumulative damage node by node, and then find the MAX value.
You're done
Regards

What dou you think about fe-safe software? (which works with major FEA programs) see:www.safetechnology.com
Does anybody work with it?
tanks in advance
