A brief overview is given of specific features that can (or cannot) appear in the dispersion spectra of traction-free elastic homogeneous plates due to anisotropy. Its effect on the overall spectral configuration and on the short and long wave trends is illuminated with a link to anisotropic traits of bulk and surface waves. Relevant classical and recent results are put together, and new points are established.
Une courte vue d'ensemble des traits spécifiquement liés à l'anisotropie, qui peuvent (ou ne peuvent pas) apparaître dans le spectre de dispersion des plaques élastiques homogènes libres est proposée. L'effet de l'anisotropie sur la configuration spectrale dans son ensemble, ainsi que sur ses limites petites et grandes longueurs d'onde, est mis en lumière à travers un lien avec les propriétés anisotropes des ondes de volume et des ondes de surface. Les résultats classiques les plus marquants, ainsi que les résultats les plus récents, sont rassemblés dans ce papier, et des points nouveaux sont établis.
