CONTACT ZONE APPROACH TO THE ANALYSIS OF INTERFACE CRACKS IN THERMOMECHANICALLY LOADED PIEZOELECTRIC BIMATERIALS

摘要

An interface crack with a mechanically frictionless contact zone in a piezoelectric bimaterial under the action of a remote mixed mode mechanical loading as well as of thermal and electrical fields is considered. Electrically permeable and electrically insulated conditions at the open part of the crack are taken into consideration. The influence of the mechanical loading as well as of the thermal and electrical fluxes upon the electromechanical values is studied.
