Galerkin's Approximation to Minimum Weight Structures with Dynamic Constraints.
Abstract
Galerkin's method is applied to the design of minimum weight structures with dynamic constraints. The problems considered include the weight optimization of a simply supported beam and a panel, with the condition that their fundamental frequencies be the same as those of corresponding uniform thickness structures. Galerkin's method is also used for the weight optimization of a semi-infinite panel and of a finite square panel, both of which have flutter speed constraints. In addition, the assumption of a symmetric thickness distribution in the flutter problems is investigated. (Modified author abstract)
