Wave propagation in phononic plates -- spectral decomposition, polarization and band gaps
Original language description
This paper reviews our very recent research focused on modelling of the phononic structures using homogenization of high contrast elastic media. We consider the Reissner-Mindlin type of the homogenized plate which involves frequency-dependent mass coefficients associated with the plate cross-section rotations and the plate deflections. Intervals of frequencies exist for which these coefficients constituting a mass matrix can be negative, giving rise to the so-called band gaps, such that the propagationof elastic waves is restricted, or even stopped. We propose a spectral decomposition based method which is suitable to compute the structure response to an external periodic loading by forces with frequencies in range of the band gaps. Numerical illustrations are given.
