机械构件中，联轴器可以用来实现相邻两根旋转轴的半永久性联接。
In machine construction, couplings are used to effect a semipermanent connection between adjacent rotating shafts.
该方法能够考虑结构及构件的二阶效应、几何缺陷和残余应力等多种非线性因素的影响，还可以考虑连接的半刚性性能。
The second order effects of the whole structure and its members, geometric imperfections and residual stress as well as the feature of semi-rigid connections can be taken into account in this method.
对于构件端部的非弹性铰，使用了半耦合的损伤函数与屈服函数。
Half-coupling damage and yield functions are adopted for non-elastic hinges at the ends of structural members.
