RELATION BETWEEN THE MAXWELL EQUATIONS AND BOUNDARY CONDITIONS IN PIEZOELECTRIC AND PIEZOMAGNETIC FRACTURE MECHANICS AND ITS APPLICATION

摘要

This paper presents the relation between the Maxwell equations and the boundary conditions in piezoelectric and piezomagnetic fracture mechanics. In addition, considering that the case after deformation (current configuration in nonlinear elasticity) is very important for these conditions, the significance of them has been studied for this case. The application of them has also been researched. Moreover, the stress field of the solid material caused by the electric field has been discussed. In the conclusion, it is briefly discussed how to determine the crack open or not, which is of vital importance for semipermeable and impermeable boundary conditions.
