Internal erosion is a major cause of failure of hydraulic structures such as embankment dikes and dams. In particular, it is initiated by localized flows, which transport soil particles through the embankment or its foundation. The detection of vibro

In this last decades, honeycomb sandwich panels have been the subject of intensive researches. Indeed, their high mechanical performances combined to a low stiffness to weight ratio result in a reduced acoustic efficiency. Therefore, many designs are
