Paper Abstract

A new experimental procedure devoted to analyse deformation patterns due to the contemporary excitation of different vibration modes (mode coupling) is proposed. The proposed procedure, based on use of holographic interferometry techniques, is particularly appropriate whenever coupled modes are expected according to FEM computation and an experimental modal analysis is required for FEM model validation. This work tests the proposed procedure by verifying the reliability of the experimental results worked out in analysing two simple specimens whose modal behavior can be confidently predicted by analytical and numerical computation.
