摘要
构造了一种新的三维奇异单元,提出了一种有效计算三维裂纹应力强度因子新的数值方法。该方法的计算结果与理论解和Newman解结果一致;与Panson等方法相比所使用的自由度数大大减小。结果表明该方法是一种高效、稳定可靠的计算方法。
In this paper, a new singular element about three dimensional cracks was formed and a new method to compute 3-D stress intensity factors was proposed. The calculating solutions obtained by present method were compared with theoretical solutions, Newman's solutions as well as other solutions. The results by present method are in good agreement with those of them. It shows that the present method is highly efficient and reliable in applications.
