Analysis of piezoelectric materials using sawtooth corrugation technique

Abstract

Abstract This paper concentrates on piezoelectric material having circular attributes. Besides implication of the corrugation to this structure is brought out. Saw tooth type of corrugation applied to this piezoelectric material with respect to the host material and its inference is the highlight of this paper. Diaphragm uses in devices and its application in the field of materials is well established. How this type of arrangement holds physically under the circumstances of steady state form is the unique study under prevailing situation. Mechanical force acting on the perpendicular direction over the corrugated piezoelectric material paves the way for implementing the required physical terms. The relation among the stress, strain and the displacement of the diaphragm is brought out. How all of them behaves in an arrangement having a circular system of host material with that of the piezoelectric material is studied. Orthotropic plate model gets handy for this type of corrugation study. Application of potential to that of the piezoelectric material and the subsequent effect over that of the field intensity and flux density with reduced dielectric constant forms the focus of attention. With diaphragm being the focus of study analytical expression is arrived for the same. Application of Gauss law solves the problem further. Comprehensively treatment of the flexural rigidity by assigning fixed boundary conditions for this context forms the last part of this problem.
