Abstract:The topic of this paper is to minimize the flexibility of a sheet with respect to its thickness and shape of boundary. These characteristics will be considered in the same algorithm, which both prevent suboptimization and mean that the user does not have to supervise the use of linked optimization tools. The refined boundary description also makes it possible to include pressure loads in this setting. Received December 4, 2000
Keywords:: shape optimization of structures   thickness optimization   design dependent load   optimality criteria method
