Abstract

This paper presents a general methodology for shape optimization for that can be applied to problems with either static strength or fatigue life as optimization objective functions and/or constraints. Research has shown that a structure optimized for the minimum boundary stress does not necessarily give the longest fatigue life. In addition as the boundary shape is changed, the critical crack locations also change. This makes it necessary to simultaneously consider flaws at a range of locations in the structure.
