| Abstract: | A scheme is developed to identify the material parameters of laminated plates using mathematical optimization and measured eigenfrequencies of the object. The object function of the optimization is defined as the difference between the measured frequencies and the computed frequencies of the laminated plates. The sensitivity of the structural eigenvalue with respect to the material parameters is analyzed. A numerical example is presented to show the feasibility of the scheme. |
