A strategy for the enrichment of experimental data is examined in connection with the problem of finite element model updating. The strategy is based on the simultaneous exploitation of the dynamic responses of various structural configurations, obtained by deliberate changes of the original boundar
In this paper, we first give the representation of the general solution of the following least-squares problem (LSP): Given a full column rank matrix X โ R nรp , a diagonal matrix โ R pรp and matrices andM([1, r]) are, respectively, the r ร r leading principal submatrices of K and M. We then conside
A best matrix approximation technique for updating the analytical model is developed using the known modal parameters. Firstly, the known modal matrix is decomposed by means of the singular-value decomposition technique. Secondly, the general updating equations for the analytical model are obtained
