Hi all,
I am a student of Music technology and for a project that I am working on I need to do an unusual FEA. I want to create a simulated model of the sound phenomenon that occurs when a sheet of material is deformed. As part of this I am required to a dynamic finite element analysis for the deformation of three types of material: a Brass, a plastic and some kind of wood. I would like have a dynamic model that could show the change in the distribution of stress across the metal as it deforms. I imagine that this should not be a very difficult thing to analyze for an experienced engineer as it is simply consists of an elliptical sheet of material that is deforming.
Please have a look at the picture to see what the system involves.

It simply consists of a sheet of brass with an elliptical shape (Major axis Roughly 1 meter and Minor 60cm) that is hung from a Microphone stand via an elastic band. When you swivel the stands handle the sheet looses its rigidity and deforms under its own weight. (…and makes an interesting sound that I am trying to simulate). The sheet of metal can be substituted with a sheet of flexible wood or plastic. My goal is to describe what is occurring within the material that causes this sound. Hope fully if i can do this i will be able to write a VST audio effect to mimic the process.
My background is in computer science so I am having difficulty with the FEA side of things so I’m hoping someone out there can offer some helpful suggestions. I realize this is probably trivial and not very relivent to most of you engineers but i could really do with some help/sugestions here.Has anyone done an analysis on a simular system like this before? Can anyone out there suggest a good software package (preferably shareware) that I should use (Ansys/Lisa)?
Thanks for any help or suggestions you can provide,
