Finite Element Analysis: A Numerical Tool For Vibration ...

The finite element method is a numerical technique that can be used to obtain an approximation of the modal parameters (natural frequencies and mode shapes) of complex structuralmechanical systems. A finite element model is typically much more detailed than an experimental model (operating deflection shape or experimental modal analysis).
