Abstract:

The work addresses piezoelectric composites with doubly periodically distributed coated fiber under antiplane shear and inplane electrical field. By applying Eshelby’s equivalent inclusion method, the eigenstrain and eigenelectricalfield concepts are introduced. Then combining the theory of doubly quasiperiodic Riemann boundary value problem, an analytical solution to the problem is obtained. Some existing solutions can be obtained as special cases of the present solution. The variations of the stress and electrical field with piezoelectric parameters of the composites are investigated.
