Reply To: Multiple bump analysis

[dlooman]

In real life the equipment would fail due to fatigue.  Solving for multiple bumps with FEA wouldn't produce a fatigue failure.  Perhaps just a single bump or only enough bumps to obtain a resonant response could be used to compute the stress range per cycle and then a fatigue calculation could be performed.  Ansys nCode could probably due both, but Mechanical could do the transient stress analysis and an external fatigue calculation could be done.
