摘要
本文用平面多区域弹塑性边界元法对增韧陶瓷搭桥模型进行了弹塑性分析。采用二次等参元和相应的半解析法，处理高次元的域内奇异积分，利用子区域法建立多区域边界积分方程．计算结果表明了搭桥夹杂的尺寸、材料特性对应力场及断裂大学参数的影响．
In this paper,the 2-D Multi-regional elato- plastic Boundarv Element Method(BEM)applied to crack bridging of particulate-reinforced ceramics is studied. The higher or-der(quadratic)isoparamatric elements are used both on boundary nad over plastic region tosimulate the field of dispalcement and stress. An effective semi-analytical method based on tri-angle polar co-ordinates is used to solve singlar regional intergrals of higher element. Theboundary intergral equations are obtained by using sub-regional method of BEM. Finally, the enhancing effect of ductile particles on brittle material is analytsed and the results are given.
