The Singularity in Two Edge-Bonded Two-Dimensional Piezoelectric Quasicrystal Wedges

Abstract

Quasicrystals have aroused great interest due to their unique atomic structure and excellent properties. In this paper, the problem of the singularity in edge-bonded two-dimensional piezoelectric quasicrystal wedges is discussed. By using Stroh formalism, we obtained a crucial matrix which related to material properties and wedge angles, for each wedge. With the help of the matrix operations, the analytical expressions for the singular order can easily be developed by simple multiplication of crucial matrix. Therefore, crucial matrix plays an important role in the final solutions, the results may be useful to design and select wedge structure in engineering applications.
