摘要
建立了一种能反映裂纹尖端应力、应变奇异性的三维等参奇性边界元，应用边界元分析方法求得了具有半椭圆形和半圆形表面裂纹厚板的应力强度因子。结果表明，采用这种计算方法得到了满意的计算效果。
The 3-D isoparametric singular boundary elements considering stress and strain singularity properties at the crack tip are formulated. The stress intensity factors of thick plate with semielliptical and half circular surface crack are presented. The calculated result is satisfactory
