“…When FE modes are corrupted, NCO is calculated by replacing FEM with E FEM in Eq. (12). The combined effect of M SEREP and E FEM , which are inaccurate due to the uncorrelated and different random numbers, results in a decrease in probability of meeting the correlation criterion.…”

“…This method can yield modes that exactly match with the experimental modes, but the procedure failed to retain the physical properties of the stiffness matrix. To overcome this difficulty, experimentally determined mode data and structural connectivity information obtained from the analytical method were used to optimally improve the deficient analytical stiffness matrix [12].…”

“…Com o intuito de apresentar uma metodologia capaz de preservar a estrutura da matriz de rigidez do sistema, Kabe [9], Caesar e Peter [10], e outros, desenvolveram algoritmos capazes de preservar a conetividade daquela matriz, mas que podiam produzir indesejado spill-over sobre o espectro não medido.…”
