摘　　要：以Ⅰ型裂纹为例，介绍和分析了运用有限元软件ANSYS计算应力强度因子的两种方法．通过对求得的应力强度因子值与解析解的比较，表明用有限元方法计算应力强度因子具有相当高的精度，并且操作简便。Taking Ⅰ-type crack for an example, this paper introduces and analyzes two ways of calculating stress intensity factor by using finite element software ANSYS. By comparing the stress intensity factor values with the analytic solution, it shows that calculating with the finite element method stands a very high precision, and is easy to operate.
