Star moving cracks problem in one-dimensional hexagonal piezoelectric quasicrystals

摘要

By using complex function method and the conformal mapping technique, star moving cracks problem in one-dimensional (1D) hexagonal piezoelectric quasicrystals (QCs) was considered. The analytic solutions of dynamic field intensity factors (DFIFs) at star crack tips were obtained in electrically permeable case. When the crack moving speed tend to zero, the present results can be reduced to the stationary ones. In absence of the electric field, the obtainable results in the paper match with the conclusions of QCs materials.
