چکیده
Piezoelectric quasicrystals have attracted extensive attention due to their unique physical and mechanical properties. This paper studies the dynamic response of multilayered two-dimensional decagonal piezoelectric quasicrystal sector plates with imperfect interfaces. Based on linear elasticity, partial differential state equations along thickness direction are derived by using state-space method. Then, virtue quadrature method Fourier series expansions, this boundary-value problem mixed boundary conditions interfaces is solved. In addition, via joint coupling matrix, field quantities in interior structure connected those external surfaces numerical instability. Finally, parameter effects angular spans, interfaces, numerically investigated where dimensionless frequencies modes exhibited.

Exact solutions are derived for three-dimensional, orthotropic, linearly piezothermoelastic, simply-supported, and multilayered rectangular plates with imperfect interfaces under static thermo-electro-mechanical loadings. In this research the imperfect interface is described as thermally weakly (or highly) conducting, mechanically compliant and dielectrically weakly (or highly) conducting. Whil...
