Refinement of Iterative Techniques in Topology Optimization

The optimal shape design of a structure is studied as a material distribution problem. The main goal of this paper is find out the optimal mass distribution for restricted mass of the construction. The analysis is carried out through FEM. The iterative procedure includes two steps. The first one leads to continues distribution of material. In other words the stiffness of the construction flows from very strong to very weak. The second iterative steps leads to discrete 0 or 1 distribution of material. The algorithm solves the problem for the same model boundary during the iterative process.
