Hello,
I have an engineering problem that involves the stress of a shaft system with multiple load points and the loads have varying direction and magnitude. The variation over time is *not* cyclic - it is random. If you ignore the variations for a moment, this is an easy linear structural FEA.
The problem is a Miner's rule fatigue calculation but because there aren't fundamental frequencies, it is very subjective and manual to sort out the variations that stack up very quickly.
Can anyone advise of a software tool that can manage the Miner's rule fatigue calculations and varying load cases? Bonus points if it will set up and run the numerous FEA load cases.
Thanks,
David
