Description
  • The software implements a model of Reissner-Mindlin plates either for direct computations in planar undeformed domains, or especially for modelling wave dispersion in periodically heterogeneous materials, including the prediction of acoustic band gaps, i.e., zones of frequencies where a wave solution does not exist due to the periodicity combined with the heterogeneity. The dispersion analysis is performed in a very efficient way thanks to the application of the homogenization theory, where the model of a homogenized plate was obtained using the two-scale unfolding method with the high contrast ansatz respected by scaling the elasticity coefficients of compliant inclusions. Consequently, dispersion properties are retained in the limit when the scale of the microstructure tends to zero. For some wavelengths, %22mass density%22 coefficients can be negative, so that intervals of frequencies exist for which there is no propagation of elastic waves, the band-gaps.
