General Information:

A student in the College of Engineering, The Pennsylvania State University who did his Master's thesis

on a finite element study of the back plate of a violin, modelling it as a shallow orthotropic shell structure.

Measurements were taken from a back plate #264 loaned by CMH: contour elevations and thickness

graduations. Comparisons were made using SAP IV computer program of modes #1,#2 and #5 with

studies via hologram interferometry. Waldman indicates that two significant conclusions were that SAP

IV is capable of predicting the fundamental vibrations in a structure as complicated as the violin back

plate; and that the shear modulus of mode #1 plays a critical role in the analysis of violin back plate
