| Abstract: | A new optimality criterion on the optimality of hole shapes is given.This criterion is that the maximally tangential stress(absolute value)on the boundary of optimized hole is smallest.A numerical proceduce for finding the optimal shape of hole based on the criterion is given. It shows that the stress concentration is smallest on the boundary of optimized hole. |

| Keywords: | optimization of hole shapes stress concentration mapping function optimization techniques |
