摘要 研究了含界面边裂纹的不同压电介质组成的复合材料在反平面荷载和平面内电场作用下的电弹场,得到了级数形式的基本解和应力强度因子,最后用边界配置法求解了应力强度因子。结果表明,在外加剪切荷载的作用下,应力强度因子与外加电场无关。 The electromechanical fields of two dissimilar piezoelectric materials containing an interface edge crack under anti-plane mechanical loads and in-plane electrical loads are analyzed. A general solution and the stress intensity factor are obtained in term of series expansion. The unknown constants are determined by boundary collocation method. Numeral results show that, under shear loading conditions, the stress intensity factor is independent of applied electric displacement and electric field.
