The stress distribution around a circular hole in a plate in uniaxial tension is well known: at the ends of the diameter aligned with the tension (the 'poles') there is a hoop stress of minus T; at the ends of the transverse diameter (the 'equator') the hoop stress is plus 3T. By superposition of two such tensions (usually unequal) we arrive at the stresses around a hole in any uniform stress field, or, equivalently, around a small hole in an arbitrary non-uniform stress field. If the hole is not small an obvious first approximation is to apply the same stress concentration factors to the stresses at the center of the 'hole', i. e. to the stresses which exist at the center of the circle where the hole is to be. This paper addresses the question of how good this approximation is, and whether it can be improved upon. 6 Refs.
