This paper deals with stress consentration problem of an elastic strip with a central hole and two supplemental holes under tension. An investigation is made for the stress mitigations due to interface effects of stress concentrations by supplemental holes. The influences of the distances between the central and supplemental holes and radii of the holes on the stress mitigations are shown. A principle of the method of solution is to distribute body forces in the interior of a strip with no hole and to determine the intensities of the body forces distributed so as to satisfy the boundary conditions at the holes. For this purpose, we apply Green's functions for body force problems of a strip. The method of solution may be regarded as a kind of the so-called indirect boundary element method with fictitious boundary.
