Abstract Scope |
Recent advances in topology optimization (TO) techniques have enabled the development of novel strategies for designing periodic microstructures in cellular materials. This work introduces a new approach that integrates numerical homogenization theory, SIMP interpolation, finite element analysis, and bi-directional TO methods within a periodic unit cell. At the core of this methodology lies the Sequential Element Rejection and Admission (SERA) method, a topology optimization scheme that iteratively filters and updates the design domain by selectively adding or removing elements. The objective is to determine the optimal microstructural topology of the unit cell that maximizes either the bulk modulus or the shear modulus. We evaluate the influence of SERA parameters on the resulting topologies and analyze the trade-offs between maximizing the bulk and shear moduli through correlation studies. The results reveal various non-trivial topological patterns, showcasing the potential of this method for the design of advanced cellular materials. |
