摘要/Abstract

摘要： This paper expresses potential function of complex variable in Fabere series and the solution in closed form is provided for the plane stress problems in piezoelectric media with elliptic inchusion.It is shown from the solution that the stress,strain,electric field intensity and electric displacement in inclusion are all constant.In addition, the electromechanical behavior of piezoelectric influence at the elliptic rim of the infinite matrix with only acting mechanical or electric load is discussed with numerical examplex.
