Research On Piezoelectric Composites' Performance Based On ANSYS

Piezoelectric composite materials (PCM) could be widely applied in smart materials and structures, since they posses the ability to tailor their mechanical and electrical properties per required by design the materials and avoid the disadvantage of easy brittleness. The Finite Element Method (FEM) has been widely applied to engineering structures design and mechanics analysis as a tool, so it would be signality to apply FEM to piezoelectric composite materials analysis. In this paper, the FEM is used to analyze some factors which affects PCM performances and orthotropy.The main content are following:1 Give a brief introduction of the FEM and the FEM software ANSYS applications in PCM analysis. And presents some commonly process and attentions in applying the FEM software ANSYS to PCM analysis.2 Analyzed the PCM performances under the affection of piezoelectric and polymer's material characteristic by FEM, and got the rule.3 Analyzed the PCM performances which affected by stickup layer's materials characteristic and its thickness under the application of FEM.4 Based on the construction principles of 1-3 type orthotropic piezoelectric composite materials, the finite element model is designed and its orthotropy is analyzed, at the same time, the length/broad ratio to PCM orthotropy is also analyzed.
