摘要
本文阐述了一种用假定应力分布的杂交有限元模型来计算裂纹问题中应力强度因子的方法。实践证明:该方法具有精度高、效率高的优点,并可以很方便地考虑体积力载荷以及裂纹表面的分布载荷,所以它的使用范围十分广泛。
The calculation of stress intensity factors using FEM with hybrid-elements based on the assumed stress distribution is expounded. It has been testified that this method is precise efficient and easy to be used to account for the load from volume force and the distributed load over crack surface. Thereore it possesses a wide variety of applications.
