A rigid line in a confocal elliptic piezoelectric inhomogeneity embedded in an infinite piezoelectric medium

摘要

An effective method is developed and used to investigate the elastic field and electric field of a rigid line in a confocal elliptic piezoelectric inhomogeneity embedded in an infinite piezoelectric medium. The matrix is subjected to the remote antiplane shear and inplane electric field. The analytical solution is obtained using the conformal mapping and the theorem of analytic continuation. Specific solutions which are compared with existing ones are provided. The characteristics of the elastic field and electric field singularities at the rigid line tip are analyzed and the extension forces on the rigid line are derived. (C) 1999 Elsevier Science Ltd.
