Description: The MSC/NASTRAN finite element computer program and a Cray XMP computer were used to study the modal characteristics of a violin with the Stradivari shape. The violin geometry was modeled using an arcs of circles scheme with PATRAN, a finite element graphics pre/postprocessor program. The violin was modeled in-vacu and with free boundary conditions. Belly, back, sound post, bassbar, neck, bridge, tail-piece, strings, rib linings, end and corner blocks are the components of the model. Mode shapes and frequencies wer calculated for free top and back plates, the violin box, and the complete violin system, including the strings. The results obtained from the finite element technique were compared to experimental data from real violins collected by other investigators.
