A combined low/high frequency dynamic identification approach is presented. The proposed hybrid technique compares experimentally extracted dynamic properties of plates such as modal frequencies and guided wave dispersion properties with the correspondent numerically predicted ones. Identification of mechanical properties of the plates is achieved by iteratively adjusting the mechanical properties assumed in finite element and semi-analytical models through minimization of the difference between experimental and predicted dynamic features.

Abstract
A combined low/high frequency dynamic identification approach is presented. The proposed hybrid technique compares experimentally extracted dynamic properties of plates such as modal frequencies and guided wave dispersion properties with the correspondent numerically predicted ones. Identification of mechanical properties of the plates is achieved by iteratively adjusting the mechanical properties assumed in finite element and semi-analytical models through minimization of the difference between experimental and predicted dynamic features.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
