2-DIMENSIONAL CONTACT ON A PIEZOELECTRIC HALF-SPACE

Due to their intrinsic electro-mechanical coupling effect. piezoelectr ic materials have been widely used in industry. In the present paper, stress and electrical field distributions in a piezoelectric half-plan e under contact load at the surface are considered. Since a piezoelect ric material is intrinsically anisotropic, stress analysis has been im peded by the complexity raised by too many material constants. Hereby, Stroh's formalism is applied in the present study to overcome this di fficulty. The solution for a concentrated force and charge acting on t he boundary of the halfspace, the Green function, is obtained in a nea t form. The non-slip and slip indentor contacts on the piezoelectric h alf-space are also formulated.
