Topology Optimization of Truss
The optimal design of skeletal structure becomes imperative both from engineering and cost considerations in recent year. Total cost of the structure mainly depends on weight of the structure and weight of the structure is proportional to material distribution within the structure.The aim of study is to achieve minimum weight of the structure under nodal displacement, stress and stability constrains. This paper deals with linear static analysis and topology optimization of the skeletal structure with two noded line elements as a non linear problem. Optimization of 6 noded, 11 member 2D benchmark truss problem is carried out, in order to find out best distribution of material between the nodes after satisfying all constrains to achieve the minimum weight of the structure. Comparison of the displacement and weight with benchmark problem is studied.Optimization has performed with the help of Hyper Work computer program tool and iteration obtained after topology optimization is discussed.
