SOLUTION OF AN INFINITE PIEZOELECTRIC MATRIX CONTAINING A CIRCULAR INCLUSION WITH AN ELLIPTIC HOLE

摘要：

　　This work mainly focused on the problem of an infinite piezoelectric matrix containing a circular inclusion with an elliptic hole under remote loadings.By using complex variable method, conformal transformation and Fourier expansion, the influence of material constant proportion between matrix and inclusion, as well as the eccentric distance of the elliptic hole on stress and electric displacement field is investigated.In this paper, the explicit and analytic results are given, which can provide scientific basis for getting optimal stress distribution by controlling the position of defect and optimizing the material constant proportion to lower the risk of fracture failure.
