Holographic And Finite Element Studies Of Vibrating Beams
Abstract
Fundamentals of time average hologram interferometry and procedures for quantitative interpretation of holograms of vibrating beams are presented. Unification of the holographic method with the finite element method (FEM) is discussed, with particular emphasi on estimation and control of errors inherent in the numerical methods. These discussions are illustrated by representative examples of holographic and FEM studies of vibrating beams.
