| 应用复变函数的Ｆａｂｅｒ级数展开方法，本文研究了含椭圆形刚性夹杂的压电材料平面问题，给出了问题的封闭解。解签表明，夹杂内的电场强度和电位移为常量。并通过算例分析，讨论了正，逆压电效应在基体孔周处的机电行为。 |
| 英文摘要: |
| This paper expresses potential function of complex variable in Faber series and the solution in closed form is provided for the plane stress problems in piezoelectric media with elliptic rigid inclusion. It is shown from the solution that the electric field strength and electric displacement in inclusion are all constant. In addition, the relative behaviors of piezoelectric influence at the elliptic rim of the infinite matrix with only acting mechanical or electric load have been discussed with numerical examples. |
