摘要
分析了刚性电极所夹持的压电陶瓷层的中平面上含有III型穿透裂纹的电弹性问题 .利用积分变换和对偶积分方程方法 ,采用绝缘型和导电型裂纹两种假设 ,分别获得了有限长和半无限长裂纹的电弹性行为的精确解析解 .并给出了相应的场强度因子和能量释放率 .
The electroelastic problem involving a mode-Ⅲ crack located at the mid-plane of a piezoelectric layer bonded to two rigid electrodes is analyzed. Using integral transform and dual integral equation method, the explicit expressions for the electroelastic field are obtained for an impermeable crack and a conducting crack, respectively. The field intensity factors and the energy release rate are given. The results for a semi-infinitely long crack are further derived.
