| Abstract: | This paper studies the simulated annealing algorithm for topology optimization of truss. A double control Metropolis procedure is developed to deal with the constraints of stress. A heuristic strategy, based on equilibrium of forces, is presented to add and delete members of truss automatically in the process of optimization. The numerical result shows that the algorithm can overcome the difficulty caused by the non_convex and star shape feasible domain in topology optimization of truss. |
