Electromechanical responses of piezoelectric fiber composites with sliding interface under anti-plane deformations

摘要

This paper deals with the analysis of electromechanical responses of piezoelectric fibrous composites with viscous interface. A model consisting of a matrix and unidirectionally arranged fibers is examined. The composite is assumed to undergo a longitudinal shear stress with a transverse electric field, thus deforms in the anti-plane state. By charactering the viscous interface with a law of linear rheology, an analytical solution is obtained for the evolving mechanical and electric fields around an isolated cylindrical inclusion embedded in an infinite matrix. The result is then used to study the overall behavior of the composite based on the Mori-Tanaka mean field approximation.
