A stress-constrained truss-topology and material-selection problem that can be solved by linear programming
2004 (English)In: Structural and multidisciplinary optimization (Print), ISSN 1615-147X, E-ISSN 1615-1488, Vol. 27, no 1-2, 126-129 p.Article in journal (Refereed) Published
We consider the problem of simultaneously selecting the material and determining the area of each bar in a truss structure in such a way that the cost of the structure is minimized subject to stress constraints under a single load condition. We show that such problems can be solved by linear programming to give the global optimum, and that two different materials are always sufficient in an optimal structure.
