Extended mean-field homogenization of unidirectional piezoelectric nanocomposites with generalized Gurtin-Murdoch interfaces

This paper presents for the first time an extended Mori-Tanaka approach aimed at identifying little-explored piezoelectric response of unidirectional nanoporous composites with energetic surfaces. The interface is simulated using generalized Gurtin-Murdoch coherent model considering nonvanishing in-plane surface stress and electric displacement. analytical solutions Eshelby’s inhomogeneity problems are obtained by solving four systems equations, generated from known macroscopic electromechanical loading conditions. dilute concentration tensors fiber evaluated exactly coupled fields, which then utilized in multiphysics homogenization scheme. reliability accuracy theory demonstrated through extensive comparison predictions composite cylinder assemblage (CCA), self-consistent method (GSCM), as well finite-element (FE) technique. New results this work demonstrate that, except transverse shear modulus, Mori-Tanaka, CCA, FE provide indistinguishable under axisymmetric, axial shear, loading, even high volume fractions small pore sizes where effects significant.
