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
