In this paper, the stress intensity factor (SIFs) of two edge cracks which emanate asymmetrically from a center U-shaped notch in a finite plate under tension were computed by the body force method. The cracks were divided into the short and long ones, and the SIFs were each investigated with respect to tendency. Then, the condition that the SIFs become nearly equal even if the cracks are asymmetric was discussed. Moreover, the approximate calculation of the SIFs were performed by using the simple formulae for evaluating the SIFs of the eccentric crack in the plate and the short symmetic edge cracks emanating from the elliptical hole in the infinite plate. The approximate accuracy was examined by comparing with the solutions by the body force method.
