I meant it from a numerical analysis/differential geometry perspective (the reason I attached the reference). While not being strictly a surface, it is characterized by a mid-surface, and a thickness t. After having that information, for each point in the mid surface, a normal vector is drawn and scaled by a magnitude of t/2 in both directions of the normal, giving a thickness of t to the object that, I should have made it clearer, is not a surface but characterized by one.
- enriquto 4y agoI don't think that a bell is correctly modelled as a shell of variable thickness. The inner surface is smooth, and the outer surface has ridges. These ridges are apparently important to the timbre, thus it may be more appropriate to consider it as a solid volume of arbitrary shape. Of revolution, if you want to stay with a one-dimensional model.

And bells are tuned by taking off material on a lathe at various positions on the inside of the bell. https://funwithbells.com/nigel-taylor/ https://funwithbells.com/nigel-taylor/ https://www.youtube.com/watch?v=JEJkMalMVv4 https://www.youtube.com/watch?v=JEJkMalMVv4
- enriquto 4y agoWow, it's good to know, thanks for the clarification!
