基于ANSYS的应力强度因子计算

Calculate the Stress Intensity Factor by the Finite Element Software ANSYS

以I型裂纹的3点弯曲试件为例,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 in three-point bending test piece as an example, this paper conducts the introduction and analysis of the use of finite element software ANSYS calculation of stress intensity factor approach. It obtained through the stress intensity factor values with the analytic solution of the comparison, showing that the finite element method using the stress intensity factor has a very high precision, and easy to use.
