Micromechanical modeling approach with simplified boundary conditions to compute electromechanical properties of architected piezoelectric composites

Abstract Architected piezoelectric composites (PCs) have recently gained interest in designing transducers and nondestructive testing devices. The current analytical modeling approach cannot be readily applied to design architected periodic PCs exhibiting elastic anisotropy activity. This study presents a micromechanical (MM)-model based finite element (FE) framework predict the electromechanical properties (EMPs) of PCs. As an example, microstructure with one-dimensional (1–3 PCs) connectivity is considered different cross-sections fibers. 3D FE models are developed. intrinsic symmetry composite used derive boundary conditions (BCs) equivalent BCs (PBCs). proposed simple eliminates need for tedious mesh generation process on opposite faces MM model EMPs 1–3 calculated from micromechanics-FE were compared those obtained solutions (i.e. micromechanics theories), homogenization by employing PBCs available literature). A quite good agreement between ones using was observed. However, excellent observed results that employed PBCs. Hence, we concluded computed enhanced effective elastic, piezoelectric, dielectric corresponding figure merit revealed suitable transducer applications.
