摘要
分析了裂纹结构应力梯度的方向性特点，进行裂纹计算并与其他方法在计算量与计算精度方面进行了比较。
Analysis is given to the direction characteristic of stress gradient in crackstructure by using three-dimensional line-type element,The purpose is considerably to reduce theoperation of computation and improve the computation precision in finite element analysis.
