Computer aided design of ferro-electric insulators

Abstract

Computer aided design of ferro-electric insulators is mostly a theoretical method of designing insultors. With the help of computer and some analytical techniques-some of the conventional insulators are,analyzed. First the electromechanical stress distribution for ferroelectric material was calculated using finite element method.'In order to formulate the finite element method, the region between two circular parallel plates has been divided into a finite number of triangular elements. An extremum function in energy density form can be developed. Then minimization technique, the potential at different the elements can be calculated. using energy vertices of A computer program has been developed for calculating electric field and electromechanical stresses for ferro-electric material placed between two circular parallel plates. The program can be readily used for designing ferro-electric insulators subject to variable electromechanical stresses.
