摘要：The stress-constrained truss topology optimization was discussed. Dr. Stolpe and Svanberg proposed a disaggregated formulation for the solution of singular optima, which included cross-sectional areas, node displacements, and internal forces as design variables. The Ε-relaxed approach aimed at finding the singular optima by well-developed structural size optimization algorithms in the context of the ground structure approach. Some global optimization methods were also proposed and a set of valuable benchmark examples with global optimality was presented. The study show that algorithms that can locate singular optima have more chance of finding the global optimum.
