| Abstract: | The identification of elastic properties of laminated composite plates from measured eigenfrequencies has been performed.
The elastic moduli of the laminates were determined by using a multilevel modeling and a two-step identification procedure.
At the first step, based on a genetic algorithm, the Young’s and shear moduli were found, but at the second one, by minimizing
an error function, the values of transverse moduli were refined.
