Abstract

In spite of the rapidly increasing number of publications on topology optimization, most of the papers are based on technologically unrealistic design constraints (e.g. “compliance”). On the other hand, most presently available iterative methods for stress and stability constraints can lead to a highly nonoptimal solution. This is due to certain computational obstacles which render some of these studies rather meaningless. In the context of trusses, three types of computational difficulties have been observed, which are associated with stress constraints, local stability constraints, and system stability constraints, with or without imperfections. The aim of this paper is to analyse the deeper reasons for these difficulties, to delimit the classes of problems in which they occur and to investigate possible methods to overcome them.
