摘要: This study employs the Element-Free Galerkin method (EFG) to characterize flexoelectricity in a composite material. The presence of strain gradient term Partial Differential Equations (PDEs) requires C 1 continuity describe electromechanical coupling. use quartic weight functions developed model fulfills this prerequisite. We report generation electric polarization non-piezoelectric material through inclusion-induced field. level set technique associated with supervises weak discontinuity between inclusion and matrix. increased area ratio matrix is found improve conversion mechanical energy electrical energy. coupling enhanced when using softer materials for embedding inclusions.
