Paper Abstract

In this paper, numerical and experimental methods for vibration mode analysis are reported. Some of the vibration modes of an aluminum plate were investigated by modeling with the finite element method (FEM). An out-of-plane electronic speckle pattern interferometer (ESPI) was the experimental method used to analyze the same vibration modes. Experimental and numerical methods are compared. These results were obtained as part of a project to identify the requirements for correlation between experimental modal measurement data and finite element numerical modal estimation.
