This paper reports the simulation results of a tri-phase piezoelectric transducer composed of PZT-5H rods surrounded by hexagonal polymer walls in a vacuum ambient. The electrical and mechanical characteristics of these transducers are simulated and predicted. The measured piezoelectric properties of the fabricated transducer at 100 kHz are found to be very much in agreement with those of the predicted design. The simulation of the designed transducer was expected to have acoustic energy channeled in the d 33 mode at resonance, with weak or no shear mode cross talk behavior from the other modes. The mechanical displacements measured were large and highly aligned along d 33 mode. This implies that tri-phasic piezoelectric transducer performs as a single device with improved mechanical and electrical response. Such designed transducers can be highly useful for the noncontact non-destructive evaluation (NDE) and nondestructive testing (NDT) with high resolution and greater depth profile of various types of material studies. Thus using several design parameters variables new transducers with desirable features can be produced for wide range of applications.

“…From this perspective, polymer composites can be treated into different categories in view of distribution fashion of piezoelectric minor domains throughout the polymer matrix (Bowena and Topolov, 2003; Della and Shu, 2007; Kar-Gupta and Venkatesh, 2007). The challenge has been to mechanistically interpret different electromechanical behaviors after introduction of ceramic inclusions (Deraemaeker et al, 2009; Li et al, 2011; Lin and Muliana, 2014; Sartorato et al, 2015; Tang and Felicelli, 2015; Uetsuji et al, 2013).…”

A finite element-based code was developed to capture the effect of particle shape on the electromechanical properties of three typical piezoelectric polymer composites. The electrical energy density and electric displacement distribution patterns were modeled by putting particles with different shapes into the model. To evaluate the reliability of investigations, differential equations were solved using Mori-Tanaka and finite element methodologies, where model predictions were appropriately consistent with each other regardless of particle shape and volume fraction of minor phase. Polymer composites filled with continuous fiber revealed similar electromechanical features irrespective of the piezoelectric nature of polymers. On the other hand, strain-and stress-induced electrical displacement distributions were sensitive to particle shape. The results suggest that densities corresponding to relative strain energy and relative electrical energy of composites containing continuous fiber inclusions are both higher than the analogous values obtained for the systems filled with short fiber and spherical particles. Likewise, the polymer composite with continuous fiber revealed improved electric displacement distribution compared to those filled with the other two types of filler. The truthfulness of the developed model was further ensured by placing multifarious particles into the host polymers, which is of vital importance from application point of view.

“…On the other hand, many numerical models have been employed by many authors to obtain the electromechanical properties for piezoelectric composites through detailed micromechanical analysis on the RVEs (or unit cells) (e.g. Li et al, 2011;Nasser et al, 2011;. Pettermann and Suresh (2000) employed the RVE to model the unidirectional piezocomposites and to study the effect of the filler concentration on the overall properties of the conventional piezoelectric composites.…”

This article is concerned with the electromechanically coupled multiscale behaviors of the heterogeneous piezoelectric materials, which consist of periodic or non-periodic distributed microstructures. A multiscale framework based on the extended multiscale finite element method is developed to capture the large-scale solutions on the coarse-scale mesh without resolving the entire small-scale features. In this method, the microscale fluctuations in the mechanical displacement and electrical potential are related to the macroscopic deformation and electrical fields through the multiscale base functions. To improve the accuracy of the multiscale method, the periodic boundary conditions are developed to calculate the multiscale base functions for those piezoelectric structures composed of periodic microstructures. Moreover, the oversampling techniques are introduced to derive the oscillatory boundary conditions to construct the base functions for those piezoelectric structures with non-periodic heterogeneous microscopic features. The efficiency and accuracy of the multiscale method proposed for the piezoelectric materials are validated through the examples where the structures consist of periodic or non-periodic heterogeneous microstructures. The results indicate that the multiscale method developed can effectively obtain the macroscale response of piezoelectric materials (displacement or electrical potential) as well as the response in the microscale (stress or electrical displacement).
