Heyhey,(adsbygoogle = window.adsbygoogle || []).push({});

I am currently doing my final year masters project which involves testing rotor blades. I am performing a stress analysis of the blades. I will be using FEA software, but I also need to do some hand calculations. I have been looking for formulas for a while now, but I am unsure which to use and how exactly I should model it.

I was thinking I could model it as a simple cantilever, but obviously this wouldn't account for the rotation. Could anyone please help me? It would be much appreciated.

Regards

Marty
