Abstract: In this paper, the measure of correlativity between test modal and computational modal was established in Hilbert space. A method judging the reliability of finite element computation and test modal analysis was given. The method was verified by analyzing thin-walled cylindrical shell practically.
Keywords: correlativity, inner product, test modal, computational modal.
