What do Guitar Strings Have to do With Dynamic Response?

Tightening guitar strings to change the sound uses the same principle as tightening head bolts to change the dynamic response of an engine block assembly. This is stress stiffening and it affects the dynamic response of a structure. One of the fundamental components in assessing nonlinear static stress is stress stiffening, but it is also the most overlooked when evaluating the steady-state dynamic response of engine assemblies.

When testing stress stiffening, it is important to understand and account for effects within the confines of a linear code. Abaqus/Standard can help with this by using the automatic multi-level substructuring eigensolver. Please refer to the attached file for the full tech brief.
