    Abstract

    This paper introduces a novel methodology for health monitoring which is applied here for composite plates. In the present study we mainly concentrate on numerical results for validating the suggested methodology. The methodology suggested is principally based on a variation of singular spectrum analysis as applied in the frequency domain. For the purposes of modeling and simulation of the response of composite laminate plates we use finite element modeling and namely a specific Finite Element modeling (FEM) scheme, which we found to be most appropriate with regards to damage diagnosis. The results validate the methodology suggested for the case of composite plates and they demonstrate good agreement with the simulated results in terms of delamination detection and localization
