Electroelastic Field Behavior in the Vicinity of the Edge of A Piezoelectric Body

Abstract

The effect of the mechanical and electric field coupling on the behavior of their characteristics near the edge of a dihedral angle is investigated. The material of the dihedral angle is assumed to be piezoelectric of the hexagonal symmetry class 6 mm. The electroelastic state is caused by a longitudinal shear strain along the edge of the dihedral angle.

The expressions for the exponents and coefficients of singularities of studied physical quantities are derived when both the exponents and the coefficients of singularities depend on the electromechanical parameters of the material.

Values of the corresponding corrections taking into account the piezomodulus for certain piezoelectric materials are calculated.
