摘要
从断裂力学的观点出发,采用边界配置法研究了含中心裂纹的矩形截面的压电材料在平面内电场和反平面变形作用下的应力场和电场的解,详细介绍了该方法的程序设计过程。作为例子,计算了能量释放率。结果表明,这种半解析半数值的方法程序编制简便,而且具有足够的稳定性和精确性。
From the view of fracture mechanics, the problem involving a center crack in a rectangular piezoelectric body under anti-plane mechanical shear displacement and in-plane electrical field is analyzed by the boundary collocation method in this paper. The program design of this method is introduced in detail and the energy release rate is calculated as an example. The result shows that the half-analytical and half-numeral method is simple, stable and accurate.
