| Abstract: |
| By using the intergral transform technique and combining with Copson methods,the scattering of SH wave in one-dimensional hexagonal piezoelectric quasicrystal with a crack is discussed.Through dual integral equations are sloved,the analytical expression of phonon field stresses,phason field stresses,phonon field displacements,phason field displacements and electric displacements are obtained.Stress intensity factor at crack tip and electric displacement intensity in electic field are defined.In the electric impermeable condition,the analytical expression of stress intensity factor at crack tip and electric displacement intensity in electic field are obtained.The study has certain theoretical value in the engineering application of piezoelectric quasicrystal materials. |
