The micromechanics modeling piezoelectric composite materials by method of homogenization Mori Tanaka: study of piezo-composite SiO2/BaTiO3

Abstract

In this work, the behavior of piezoelectric composite has been studied in terms of prediction, in order to contribute to understanding the piezoelectricity, perroelectricity phenomenon of these materials. The materials with the piezoelectric intrinsic properties have been added fillers to matrix to obtain the piezoelectric composites materials. The Mori-Tanaka model has been used to predict the mechanical behavior, which is part of the electromechanical formulation. The use of Mori-Tanaka model is based on its compatibility with the composites at high fiber volume content. The results from the Mori-Tanaka model have been compared to Voigt and Reuss models. The models have been simulated using programming language to determine stress-strain behavior.
