Abstract

Abstract The time-harmonic wave propagation in three-dimensional and multilayered transversely isotropic one-dimensional quasicrystal nanoplates is investigated based on the nonlocal strain gradient theory. According to the time-harmonic solutions of the extended displacement (i.e., phonon and phason displacements), the elastic wave problem is converted into a linear eigenvalue system from which the extended displacement and stress are expressed in terms of the eigenvalues and eigenvectors. The dispersion curve is obtained by the propagator matrix method. Numerical examples are provided to show the influence of the nonlocal parameter, strain gradient parameter, stacking sequence and wavenumber on the dispersion curves and mode shapes in layered quasicrystal nanoplates.
