Abstract
Structural optimization, defined as the evolution of a structural design that satisfies a set of functional requirements and that, in terms of a predefined criterion, is the best of all such acceptable designs is discussed. Structural optimization problems are presented and analyzed. The problems are classified according to major constraint-e.g., natural frequency, flutter, dynamic response, and chatter stability. Each class is discussed. Approximate analysis techniques and some recent work on optimization methods, as applied to the design of structures, are presented. Structural optimization problems in need of further investigation are summarized.
