Ringing in the Blog

Deformed structural models can usually be animated, depending on post-processor.  While this can be very useful, I thought it might be interesting to hear how a model sounds. I found a dimensional reference recently that allowed me to craft a very basic Abaqus Explicit model which should sound like the real thing.

Using symmetry, I was able to build the model with less than 1000 nodes.


The sound propagation is still very approximate, as sound only emanates from  a single location on the surface of the bell.  I'll follow up on this model by adding an acoustic mesh to allow pressure waves to propagate towards receiver location properly.  Still, it sounds kind of neat., and not too far off from the real thing for a first cut.
