Abstract
A fundamental problem in the design of laminate composites is strength degradation in the presence of stress concentrating features such as flaws and attachment holes. This paper presents a scheme for optimizing material design so as to maximize strength in the presence of flaws. This optimization occurs over a landscape littered with local maxima, which is reliably traversed by a heuristic approach such as a genetic algorithm. A simple example is presented which highlights the benefits and drawbacks of considering flaw tolerance in laminate design.
