When the product fails /then/ you go on the course and read the books.

RE: Stress analysis
It would take too long to answer the original question so it's better to read the appropriate design standard for that component, and pehaps read some guidelines on how to use FE in fatigue assessment. NAFEMS probably has some.

RE: Stress analysis
clearly the original poster doesn't know enough to correctly apply a "magic bullet" solution ...
but to be helpfull to vikrameng, i agee with johnhors, get a book about fatigue analysis, maybe a training course (but i believe you have to know something of the topic to get the most out of these). sorry, but sometimes you have to put in the "hard yards" ...
good luck
RE: Stress analysis
As you may already realized, you have start from basics to understand fatigue. There are some resources on the web to get you started

Also look at smartsim.org. If you google you can find some resources on fatigue anlaysis using ANSYS.

The software should come with some sort of training manual or help documentation. If you don't have those then try online to find a tutorial. Or send one of those "spam" emails to your friends asking if they have a tutorial :). Having said that I should add that it is always good to work out the problem using simple hand calculation first. It is very important to understand the theory in fatigue analysis. Since you have already done a static analysis the results from that should be helpful in your hand calculations.
