Structural Optimization Using Optimality Criteria

  • Conference paper
Computer Aided Optimal Design: Structural and Mechanical Systems

Part of the book series: NATO ASI Series ((NATO ASI F,volume 27))

Abstract

First, the historical background leading to the optimality criteria approach is discussed pointing out the role of the traditional design methods on one hand, and Prager’s work based on variational principles on the other hand as the two motivating influences. This is followed by the formal development of the method utilizing the separability properties of discretized structures or models. The importance of the single constraint case is pointed out and the associated particularly simple yet powerful optimality criteria is presented followed by extension to multiple constraints. Examples are used to illustrate the approach for displacement, stress and eigenvalue related constraints.
