How to do the fatigue analysis by using ANSYS

How to do the fatigue analysis by using ANSYS

How to do the fatigue analysis by using ANSYS

(OP)
Dear Everyone,

Now,I am trying to work on fatigue analysis in tractor frame but there are no good examples for me to practise with fatigue function in ANSYS. I beg everyone for an example of fatigue analysis.Please help me for it.

Yours Sincerely

RE: How to do the fatigue analysis by using ANSYS

Here's a few websites to start you off with:

http://ansys.net/ansys/?mycat=search&mytype=All&mysort=alpha&mystring=fatigue
http://www.ansys.com/products/fatigue.asp
http://www.caeai.com/papers/Fatigue_ANSYS.pdf
http://www.dermotmonaghan.com/forums/viewthread.php?tid=7

Get yourself some good notes on fatigue, particularly those discussing issues such as:

-> The Mean Stress relationships
-> S-N and e-N curves/analysis
-> Goodman, Gerber, Modified-Goodman, Morrow, Soderberg relationships
-> Haigh Diagrams
-> Interpretation of fatigue data (strain data, mean/alternating stresses, etc.)
-> Check any book on strength of materials. Here you'll find a lot of theoretical and probably some practical information, including figures for endurance/fatigue limits for engineering materials

Fatigue is a BIG subject area, as no doubt you'll find out.

Cheers,

RE: How to do the fatigue analysis by using ANSYS

You could also use a specific fatigue software like FE-Safe or FE-Fatigue that takes the results file from anays and uses traidtional fatigue theories to compute fatigue life and potential failures. I dont know if you have that software though.
