Sažetak
The future of navigation cannot be imagined without nanotechnology. It is increasingly implemented in electronic and computer components of every modern automatic system. In manufacturing of these components such as sensors, transducers, actuators and other electromechanical devices, piezoelectric materials have been and will be used. It is well known that various defects in material, such as dislocations, cracks and inclusions can adversely influence on the integrity and performance of such devices. Therefore, it is very important that the behaviours of these defects are analyzed under real electromechanical load. These defects can be observed on very small dimensions, at atomic level. This paper analyses a screw dislocation around finite crack in a hexagonal ceramic crystal subjected to antiplane mechanical and in-plane electrical loads. 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 are obtained in MatLab and they are presented in 2D and 3D graphs.
