Abstract

Numerical analysis of PZT-Polymer composites using pb-3 Ritz method H. M. Shodja, M. T. Kamali & A. Rasekh Department of Civil Engineering, Sharif University of Technology, Iran Abstract An energy based formulation of piezocomposites and a general 3-dimensional Ritz method for the analysis of piezocomposite solids of arbitrary shape and arbitrary width to thickness ratio are developed. The displacement fields and the electric potential function are approximated using special base functions, which satisfy boundary conditions through pb-3 method. Furthermore, an innovative remedy will be given to treat the problem of the discontinuities in strain fields and in electric displacement across the interfaces. An important feature of the present method is that, it can be used to analyze arbitrary shaped piezoelectric plates with high accuracy without the need of mesh generations and hence eliminating its associated difficulties. The accuracy of the present analysis for some numerical experi
