Abstract

In this paper, a new dynamic reanalysis method for composite structures is presented. First we construct an iterative format on the basis of the matrix perturbation theory. By introducing a pair of initial eigensolution, we can obtain the natural vibration mode of the modified composite structure, and then use the Rayleigh quotient to compute the corresponding natural frequency. In this way, the computation accuracy can be greatly improved. Finally, a numerical example of composite laminate is included to demonstrate the validity of the proposed method.
