Abstract EN
Interaction of a screw dislocation with wedge-shaped cracks in one-dimensional hexagonal piezoelectric quasicrystals bimaterial is considered.
The general solutions of the elastic and electric fields are derived by complex variable method.
Then the analytical expressions for the phonon stresses, phason stresses, and electric displacements are given.
The stresses and electric displacement intensity factors of the cracks are also calculated, as well as the force on dislocation.
The effects of the coupling constants, the geometrical parameters of cracks, and the dislocation location on stresses intensity factors and image force are shown graphically.
The distribution characteristics with regard to the phonon stresses, phason stresses, and electric displacements are discussed in detail.
The solutions of several special cases are obtained as the results of the present conclusion.
