Abstract
It is briefly presented an on-going activity on the dynamic characterisation of aluminium foam sandwich plates. The bounds of the eigenvalues representing the wave travelling in an infinite plate are given for a given interval of stiffness and mass in the foam part of the model. The resulting dispersion curves are thus associated to the given variations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
