EXACT SOLUTION OF ANTIPLANE STRAIN PROBLEM FOR THE PIEZOELECTRIC MATERIALS WITH AN ELLIPTIC HOLE
Hu Yulin,Hou Mishan
The electric field boundary conditions for the holes and voids at the material surfaces were considered as the homogeneous or constant boundary conditions by the previous researches.In this paper,in consideration of air medium inside the hole defects acting on the electric field, a coupled field of antiplane strain problem for the piezoelectric material with an elliptic hole is analyzed with an expression for potential function of complex veriable in Faber series. An exact solution of the problem is given.These results are compared with some results of previous researches by using homogeneous boundary conditions.
