    Abstract

    Combined experimental-numerical methods are presented with the goal of obtaining material stiffness for composite materials. The identification is based on eigenfrequencies for a free rectangular plate, because excellent agreement between measured and calculated eigenfrequencies can be obtained. The numerical identification problem is formulated as an optimization problem and in one experiment we obtain all the involved moduli.

    The total approach consists of experiment, numerical eigenvalue analysis, eigenvalue sensitivity analysis, optimization, and error estimation. Recent results from these different parts of the approach are commented and the general conclusion is that the method has several significant advantages compared to traditional determination of material moduli. An overview of the state of the art is intended.
