Some Approaches for Shape Finding in Optimal Structural Design

  • Conference paper

Part of the book series: Lecture Notes in Engineering ((LNENG,volume 63))

Abstract

Shape optimization by moving boundaries is now a well established technology, which enters commercial programs. Following the philosophy of Schmit [1], Fleury [2] and many other contributions, the movable shape problem is described by means of a blending function, which is governed by a comparatively small number of variables. This property disposes the approach favourable to mathematical progamming (MP), which can handle all types of objectives and constraints very easily. However since we have to preselect the position of the moving boundary as well as the type of the blending function, the process of finding an optimal shape is quite predetermined. We are for instance not able to create automatically voids.
