And the results obtained are compared with those obtained with the program of finite elements COSMOS.enghttps://v2.sherpa.ac.uk/id/publication/issn/0277-786Xinfo:eu-repo/semantics/conferencePaperApproximation theoryFinite element methodHolographic interferometryImage analysisNatural frequenciesPlates (structural components)ResonanceSpeckleDigital speckle pattern interferometry (DSPI)Finite elementsPlate vibration modesTime-average holographic interferometryVibrations (mechanical)2021-04-12Rueda, E.Angel, L.Velasquez, D.10.1117/12.591650
