摘要
This paper presents a comprehensive range of results of mode I stress intensity factors for the embedded elliptical cracks in finite thickness plates under uniform tension. The hybrid boundary element method developed by the author is used to calculate the stress intensity factors. The analyzed ratio of crack depth to crack length (b/a) Is 0.25, 0.5 and 1.0: the ratio of crack depth to plate thickness (b/t(1) and b/t(2)) ranges from 0.0 to 0.8. The present normalized stress intensity factors are also compared with Isida's results obtained by the body force method. The two results agree excellently with each other, with a maximum difference of 2%.
