Conclusion: While the forearm in complete supination, the radius shifts to the dorsal and distal side, and the capitulum ulnae is at the volar side of the notch ulnae.
结论：前臂完全旋后时，桡骨向远侧、背侧移位，尺骨头靠在尺骨切迹的掌侧面。

With the increase ofnotch root radius and the decrease of stress concentration coefficient, the tensile strength decreased.
材料的抗拉强度随着材料缺口半径的增加及应力集中系数的降低而降低。
3
The stress triaxiality and equivalent plastic strain distributions at the minimum cross-section of specimens with different notch root radius are similar for such three kinds of materials.
