摘要
提出了一个新的孔形优化准则──孔边绝对值最大的切向应力最小,并给出了基于这种优化准则寻找最优孔形的方法,在所得的孔洞周边,应力集中程度最小.
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.
