Electro-mechanical coupling properties of piezoelectric nanocomposites with coated elliptical nano-fibers under anti-plane shear

Size-dependent effective properties of anisotropic piezoelectric composites with piezoelectric nano-particles

“…According to the coupling interface theory [15][16][17][18], the boundary conditions at the interface are expressed as follows: The physical meaning of the last equation is that the surface energy around the nanoparticles results in the jump of the electric displacement.…”

“…The surface effect of polymer-PZT piezoelectric composites on the piezoelectric, mechanical and electromechanical characteristics was investigated by Kerimov et al [16], and a reasonable mechanism explaining this effect was suggested. Combining the electro-elastic surface/ interface model, the generalized self-consistent method and the mapping method, an electro-mechanical model is developed to evaluate the effective coupling properties of piezoelectric nanocomposites with coated elliptical nanofibers [17]. This surface/interface model was also used to predict the electro-mechanical behavior of piezoelectric thin film with square nanofibers under anti-plane shear [18].…”
