The dynamic fracture of a crack in a functionally graded one-dimensional (1D) hexagonal piezoelectric quasicrystals (PEQCs) subjected to a time-harmonic elastic SH-wave is studied by using integral transform technique and Copson method. It is assumed that the crack surface is a partially permeable boundary condition and the material properties vary continuously as an exponential function. With the help of the Fourier transform, the boundary value problem of partial differential equation describing fracture problem is formulated to three pairs of dual integral equations, which are numerically solved by Copson method. Explicit expressions for the electroelastic field including phonon and phason stresses and electric field on the crack face are determined. The dynamic intensity factors of the electroelastic field are obtained in closed form, and some special cases of obtained results are discussed. On the basis of theoretical analysis and numerical simulation of the established models, numerical analysis was then conducted to discuss crack length, gradient parameter, electric boundary condition, electric loading, incident angle, amplitude, and wave number on the fracture characteristics of material. The research of this paper will provide a theoretical basis for nondestructive testing, optimal design, and reliability analysis of materials and will enrich the research content of fracture mechanics of multi-field coupling materials.

In this paper, a mathematical study is carried out to investigate the reflection phenomenon of plane QP waves at mechanically traction‐free and dielectrically charge‐free boundary surface of a pre‐stressed rotating piezoelectric half‐space. The microstructure effect (flexoelectric effect) is considered in the piezoelectric half‐space along with micro‐inertial effect as well as strain gradient effect. Due to the reflection phenomenon at the free surface, five kinds of coupled elastic waves are generated. The reflection coefficients are evaluated numerically. Graphs are plotted, and detailed discussion is presented to elaborate the effects of initial stresses, rotation, and flexoelectric coefficient on the reflection coefficients. It is observed that aforementioned parameters have remarkable influence upon the reflection coefficients of the reflected waves.
