Thanks for all the input.
I am using 6061-T6 aluminum for the material which I believe has a fatigue strength of 14ksi.
At first I was taking the 14ksi divided by three (4667 psi) and using this value to compare to the FEA results and trying to modify the design to pass this limit. The...
I hope not, I am new to MIL-STD-810F and that is what I was using as a basis and was told by my fellow co-workers to take the fatigue strength and divide by three and make sure the stress is below this value.
I have the FEA results and I am trying to decide if the part will function under the...
What is a good basis for determining if a part will fail due to fatigue damage? Is it valid to take the fatigue strength of the material divided by three (3 sigma approach) and use this number as the limit?
I am trying to design an antenna bracket that will pass the vibration exposure limits specified in mil-std-810. I modeled the bracket into Solidworks and ran FEA analysis and I have the stress results in each direction resulting from the Grms loading per Miles equation. Using the 3-sigma...
