Abstract

As a result of their wide use in the form of sensors and actuators, much interest has been focused on the reliability and failure behavior of piezoelectric materials. This leads to the need to develop techniques for predicting crack growth under monotonic and fatigue loading (both mechanical and electric). To this end, accurate methods are required for calculating stress and electric flux density intensity factors in these materials. The solution is affected by the mechanical and electrical coupling, as well as material anisotropy in its poled state.
