| Summary: | 碩士 === 國立成功大學 === 航空太空工程學系碩博士班 === 100 === One of the most important problems in the design of plate structures is to determine and minimize the stress concentration due to the presence of holes and other discontinuities. 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.
