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.

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.
