The formulas for the stiffness matrices and load vectors of analytical elements are deduced.

将上面的半解析有限元法应用于弹塑性断裂力学中的Dugdale模型，分别构造了基于Ⅰ型和Ⅱ型Dugdale模型的裂纹解析元，并建立了解析单元的出口刚度阵和荷载向量的列式。

By the theory of complex functions, dynamic propagahon problem on Dugdale model of mode Ⅲ interface crack for nonlinear characters of materials was studied. The general expressions of analytical solutions are obtained by the methods of serf-similar functions. The problems dealt with can be easily transformed into Riemann-Hilbert problems and their closed solutions are attained rather simple by this approach.

通过复变函数论的方法，对材料的非线性特性下的Ⅲ型界面裂纹Dugdale模型的动态扩展问题进行了研究，采用自相似函数的方法可以获得解析解的一般表达式，应用该法还可以很容易将所讨论的问题转化为Riemann-Hilbert问题，并可以相当简单地得到问题的闭合解，利用这些解并采用叠加原理，就可以求得任意复杂问题的解。

I just want to tell you, our war history is super duper glorious. Hand-to-hand battles where your bayonet is blood red, we've fought big and small some thousand times. And now, now we are the crack troop of the full mechanized and armoured forces in China. So nobody cries anymore. Don't let the vetarans laugh at you. Vets love to see the roodies cry actually. I remember I used to cry myself apiece when I joined, and my old company commander laughs at me till now…Oh no, my old commpany commander has left already. When he left I cried again…

我是要告诉你们，咱们团战史老鼻子辉煌，刺刀见红的战，打过得有大小几千次，现在呢，现在也是咱中国全机械全装甲化的王牌部队，所以谁也不兴再哭啦，别让老兵看笑话，老兵可就爱看新兵哭，想想我入伍那时候也是哭个黄河决裂，让老连长一直笑话到现在……不，老连长现在可走啦，他走的时候我可又哭啦……
