Hydroxyapatite bioceramics 被使用有限元素方法模仿(女性) 。孔，洞形状，快克的角度和陶艺上的另外的参数的影响被分析。结果随在快克和水平方向之间的角度的增加显示出那，压力紧张因素 K 我逐渐地减少，但是压力紧张因素 K II 起初增加然后它减少。当在快克和水平方向之间的角度是 TSMC 的 45 0.18 m 标准互补金属氧化物半导体逻辑时， K II 的价值到达最大值，布局尺寸是 229.04 m c 压缩机片的性能作为 BLS 质量被改进流动率增加。最佳 BLS 是大约 1.2% 。公司耀 ? 耀？？

英文摘要：

Hydroxyapatite bioceramics is simulated by using finite element method （FEM）. The influences of porosity, hole shape, angle of crack and other parameters on the ceramics are analyzed. The results show that with the increase of the angle between crack and horizontal direction, the stress intensity factor KⅠ decreases gradually, but stress intensity factor KⅡ increases at first and then it decreases. The value of KⅡ reaches maximum when the angle between crack and horizontal direction is 45°. KⅠ and KⅡ rise with the increase of porosity, and they are almost the same for the circular and hexagonal holes. For elliptical holes, KⅠ and KⅡ reach maximum when the long axis of ellipse is perpendicular to the loading direction and they reach minimum when the same axis is parallel to the loading direction. Moreover, with the increase of the angle between the long axis and loading direction, KⅠ and KⅡ increase gradually.
