By applying contour integral method and high-order displacement functionsof MM,we obtain the accurate stress intensity factors of mixed-mode crack.Then,the open crack propagation of the mixed mode I and II is simulated by means oftheories of linear elastic fracture mechanics.This provides a simple and effectivenumerical way for crack evolvement studying.

接着，文中采用围线积分法和流形方法的高阶位移函数来计算得到比较准确的混合型裂纹尖端的应力强度因子，然后基于线弹性断裂力学的裂纹扩展准则，用流形方法实现了平面I-II混合型张裂纹扩展的数值模拟，为数值方法研究裂纹的演化行为提供了一条简单而有效的途径。

Flange height and lip thickness are limited to the drawing ratio of the sheet metal in the convectional hole flanging process. Necking or fracture tends to occur before the required flange height being achieved which is unfavorable for subsequent assembly operations.

般金属板材在进行孔凸缘冲压成形时，凸缘高度和轴壁厚度通常受材料伸长率的限制，往往在未达所需凸缘高度前，板材即发生颈缩或破裂的现象，不利后续组装加工。

If an object sliding along the contact surface, the two of the contact surface of the convex part of the collision, a fracture, wear, created obstacles to the movement.

如果一个物体滑动沿接触表面来看，两者的接触面的凸角部分的碰撞，断裂，磨损，制造障碍，把运动。

Methods Fourteen cases of soldiers'scaphoid fracture were treated with screws by palmside retrograde internal fixation. Cooney's clinical evaluation system was used to evaluate the results according to wrist pain, moving extension and gripping strength.
