Abstract

An inverse method for material parameter estimation of elastic, piezoelectric and viscoelastic laminated plate structures is presented. The method uses a gradient based optimization technique in order to solve the inverse problem, through minimisation of an error functional which expresses the difference between experimental free vibration data and corresponding numerical data produced by a finite element model. Applications are presented using a simulated test case for an adaptive plate.
