Optimality Criterion Techniques Applied to Structures Composed of Different Element Types.

Abstract

The optimality criterion design method, developed by Khan, Willmert and Thornton which exploits the concept of one most critical constraint, has been extended in this paper to handle more complex structures, specifically ones composed of several different types of elements. The elements considered were the truss, and two different plane stress elements: a constant strain triangular element and a rectangular symmetric shear panel. The optimality criterion method treats multiple load conditions and stress and displacement constraints. A wing-box structure is considered as an example to demonstrate the efficiency and simplicity of the method. (Author)
