Truss Topology Optimization by a Displacements Based Optimality Criterion Approach
Abstract In this paper we present a displacement based method for maximum stiffness truss topology design. The ground structure approach is used, and the problem is formulated in terms of displacements and bar areas. This large, non—convex optimization problem can be solved by identifying an equivalent, unconstrained and convex problem in the displacement which can be solved by a non—smooth, steepest algorithm. In this method we circumvent the explicit solving of the equilibrium equations and the assembly of the global stiffness matrix. A large number of examples have been studied, showing the attractive features of topology design as well as exposing interesting features of optimal topologies.
