Abstract

A combined numerical/experimental method for the identification of six: elastic material moduli of generally thick composite plates is proposed in this paper. This technique is used in composite plates made of different materials (i.e. hybrid plates) and may be used in specimens with general stacking sequences. It makes use of experimental plate response data. corresponding numerical predictions and optimisation techniques. The plate response is a set of natural frequencies of flexural vibration. The numerical model is based on the finite element method using a higher order displacement field. The model is applied to the identification of the elastic moduli of the plate specimen through optimisation techniques, using analytical sensitivities. The validity, efficiency and potentiality of the proposed technique is discussed through test cases.
