This study systematically investigates the effective elastic properties of 1D hexagonal quasicrystal (QC) with spring-type imperfect interfaces. The numerical results show that the presence of imperfect interfaces reduces the effective elastic constants to some extent, indicating the important role played by the interface in the elastic properties of QC composites.
Considering the spring-type imperfect interfaces, the effective elastic properties of one-dimensional (1D) hexagonal quasicrystal (QC) are investigated systematically. The spring-type imperfect interface between QC matrix and inclusion is an ultra-thin, soft and weakly conductive interface. The Mori-Tanaka method is presented to determine the effective elastic constants of phonon, phason and phonon-phason coupling field. The numerical results are provided to show that the existence of imperfect interfaces reduces the effective elastic constants to some extent. It indicates that the interface plays an important role in the elastic properties of QC composites. Besides, the effective elastic constants are also subject to the aspect ratio and the volume fraction of inclusions.
