【摘要】 用复变函数解析延展原理，研究了集中载荷作用下的不同压电材料反平面应变状态的共圆弧电渗透型界面裂纹的耦合场；对单个圆弧裂纹，给出了封闭形式的复函数解和场强度因子．结呆表明，在裂尖处耦会场有（1／2）阶的奇异性．更多还原

【Abstract】 This Paper research on coupling field for antiplane strain problerns of the circular- arc electrically permeable slit cracks between bonded dissimilar piedectric materials under the concentrated forces by using analysis continuation principle of functions of complex variable. Soutions in closed-form of the complex potentials and the field intensity factors are given for a single circular-arc crack. It is shown from the solutions that the coupled field has (1/2) type of singularity at the crack tip更多还原
