含椭圆孔的压电材料反平面应变问题的基本解

Basic Solution of Antiplane Strain Problems for Piezoelectric Media with an Elliptic Hole

用复变函数研究了含椭圆孔的压电材料反平面问题的基本解和裂纹尖端的场强度因子．结果表明：应力强度因子与普通材料的应力强度因子相同，而电位移强度因子与前者有相同的表达形式．

A basic solution to the antiplane strain problem with an elliptic hole for the piezoelectric medium is derived with expressing the complex potential, and also gave field intensity factors at the crack tip. The results indicated that the stress intensity factor is the same as the factor of the general isotropic material, and the electric displacement intensity factor has the same expressions of the stress intensity factor.
