Application of Strength and Weight Criteria

Abstract

Strength criteria constitute the fundamental constraints that must be taken into account in any optimal design. Such constraints are local in nature and are stated in terms of the components of the stress tensor. At the present time various theories of strength have been investigated and some of them have been extensively applied in optimal design research. The choice of any specific strength criteria, or the use of such approximate criteria, depends on the structural materials, the type of loads, the use of a specific computational scheme, and on other factors.
