Abstract
The problems of the tension of a semi-infinite plate having a semi-elliptical notch with a crack are analyzed by the body force doublet method. Quite accurate values of the stress intensity factor for a crack of arbitary size can be obtained by using the stress field due to a pair of point forces (doublet) in an infinite plate with an elliptical hole. Furthermore, the error due to the use of equivalent crack length, which is the sum of notch depth and crack length, is discussed.
