I'm working on Developing a spline fatigue prediction method. I've reviewed different papers and articles about the different methods of fatigue prediction (LDR - Continuum damage mechanics - Multiaxial and variable amplitude loading), yet I can't really find what I'm looking for depending on the criteria of choosing the method (Accurate, easy to implement) and the problem conditions (Torsional fatigue, splined shaft, alloyed).
Hi,
It depends a little on what you want. If you look for a decent calculation that is gives safe shaft designs, I recommend a look in the FKM guideline Analytical Strength Assesment (https://www.vdmashop.de/Forschungshefte--FKM-/Analytical-Strength-Assessment-6-th-Edition-998.html?XTCsid=mttgos8jjj863bd1e4f9g4hoj1). At least it will tell you if any newly developed method is close to egineering practice.
It is expensive, but your library might have it.
Regards,
I would suggest the Smith-Watson-Topper multiaxial fatigue criterion. It gives reasonable results in contact problems (at least in fretting fatigue cases) and the critical plane implementation is straightforward.
