There is a great deal of information on this classical problem. Because the stress concentration is of more concern, this paper tries to find optimal shapes of holes in infinity plates under uniaxial and biaxial loading conditions. The optimal shape offers the lowest possible stress concentration , whose hole area keeps constant.
