Three-Dimensional Thermoelastic Contact Problem of One-Dimensional Hexagonalpiezoelectric Quasicrystals Coating

Abstract

This article investigates the mechanical properties of one-dimensional hexagonal piezoelectric quasicrystals (1D HPEQCs) coating under normal force and frictional heat by using the discrete convolution-fast Fourier transform (DC-FFT) algorithm-based hybrid element method (HEM). The general solutions in the two-dimensional Fourier domain are obtained by combining the two-dimensional Fourier transform with strict operator theory and the Almansi' theorem. The DC-FFT algorithm-based HEM is used to solve the problem of transforming the fundamental solution in the Fourier domain into the spatial. The solutions of force and displacement in phonon and phason fields are obtained. The results indicate that current density has a significant impact on the phason field, and an increase in current density enhances the properties of the phason displacement.
