Abstract

A generalized stress criterion for optimal design is proposed and a corresponding algorithm is developed. The new method is a combination of criteria method and mathematical programming. It is suited for size and topology optimization of a general structure made of multiple material groups and subjected to multiple loading cases. The stress, displacement, local and global buckling constraints can be considered. Two standard problems, where the fully stressed design fails, are solved to demonstrate the reliability of the generalized stress criterion. The other examples demonstrate that the new method is also suitable for size and topology optimization problems of membrane and shell structures.
