Numerical and practical experiments for maximally stiff structure based on the topology optimization theory and the FEM

Abstract

In this study, numerical studies for a maximally stiff structure based on the topology optimization theory and the FEM are carried out, and the result of several practical tensile tests for the optimized structure was shown. The specimens for tensile testing were made using 3D printer. The numerical studies included filtering radius based examination. The thickness of the optimized model was also investigated, assuming the displacement of the optimized model to be the same as that of the initial model.
