英文摘要：

By using the complex variable function method and the conformal mapping technique,the antiplane problem of one-dimensional hexagonal piezoelectric quasicrystals with a circular hole with four cracks is analyzed. The solutions of the stress intensity factors and electric displacement intensity factor is given in analytical form. For some special cases,such as a circular hole with symmetrical four cracks,a circular hole with three cracks,a circular hole with two collinear cracks,a circular hole with a single crack,a cross crack and a T shape crack in one-dimensional hexagonal piezoelectric quasicrystals,the analytic expressions of the stress intensity factor and the electric displacement intensity factor can be obtained by taking a limiting process from our present solution.
