Abstract

This paper presents a study on the electromechanical interaction between a compliant surface electrode and a semi-infinite piezoelectric material. Using integral transforms, general expressions of stresses, displacements, electric potential and electric displacement have been obtained for symmetrically deformed electrode. For surface electrode subjected to uniform displacement, the normal stress at the edges of the electrode displays a square root singularity. Such a stress singularity will eventually induce the initiation of crack and introduce mechanical and electric instability.
