Fig. 5From: Measurement of 1–10 Hz 3D vibration modes with a CT-scannerMeasured displacement fields of the five first modes \({{\varvec{\Phi }}}_i^{\text {PGD}}\) in the x, y, z directions (here shown on the numerical mesh yet computed on the boxed mesh composed of 81 space degrees of freedom). The amplitude is to be associated with the 1500 time amplitudes normalized angle-wiseBack to article page
