The larger natural holes in bone are not involved in failure because of the special material distribution in their vicinity. In this paper, a procedure was developed that designs the nonaxisymmetric functionally graded material distribution around a hole in a plate in an attempt to mimic bone for increased strength at small weight increase by minimizing a failure index (stress/strength ratio). Nonaxisymmetric graded material distributions were represented by a generic continuous function of eight design variables. The results show that the optimal nonaxisymmetric functionally graded plate with a hole has a material distribution pattern similar to that found in bone, and the load-carrying capability of the plate can be greatly increased at small hole weight ratio#.
