On Screw Dislocation Near a Crack in PZT Material Under Electromechanical Load
The piezoelectric materials have been widely used in modern electromechanical devices and engine systems. It is well known that various effects in material, such as dislocations, cracks and inclusions can adversely influence the integrity and performance of such devices/systems. Therefore, it is very important that the behaviors of these defects are analyzed under real electromechanical load. In this work is analyzed a simple continuum model of a single screw dislocation near a finite crack in a hexagonal piezoelectric crystal subjected to electromechanical load. The linear piezoelectric theory, complex analytic functions and conformal mapping method are used, and the forces acting on a dislocation are determined. The numerical results for piezoelectric PZT ceramic material are obtained in MatLab and they are presented in 2D and 3D graphs.
