✦ Synopsis

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 (bit, and bit2) ranges t~:om 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%.

The weight function for the surface point of a semi-elliptical crack in a plate of finite thickness has been derived and tested against numerical data available in the literature. Derivation was accomplished by using the universal weight function form and two reference stress intensity factors. It w
