摘要
本文探讨了用在奇异项上叠加普通有限元的方法,来计算应力强度因子的问题。它推广了钱伟长等人的工作,可用于Ⅰ、Ⅱ型及Ⅰ、Ⅱ混合型裂纹的应力强度因子的计算。
An approach based on the superposition of normal finite element on singular terms for the calculation of stress intensity factors is proposed and the work done by prof. Chien Wei-Chang&others is extended in this paper. This approach can be used to calculate the stress intensity factors for mode Ⅰ and mode Ⅱ as well as for the mixed mode.
