... in fabricated structures without altering their geometry remains a major challenge. Here, we introduce an inverse design approach to tune buckling behavior in magnetically active structures through the variation of applied magnetic stimuli. Our proposed magneto-mechanical topology optimization formulation...

...Jianwen Bao; Zhaoyou Sun; Pai Liu; Yangjun Luo Topology optimization is among the most effective tools for innovative and lightweight structural designs. Multi-material design is considered to achieve better structural performance than single-material design. To significantly reduce the design...

...Bastian Telgen; Ole Sigmund; Dennis M. Kochmann We introduce a computational framework for the topology optimization of cellular structures with spatially varying architecture, which is applied to functionally graded truss lattices under quasistatic loading. We make use of a first-order...

.... To enable hole nucleation in the level set topology optimization framework, the concept of topological derivative [ 13 , 14 ] has been introduced. The topological derivative represents the change of objective function when an infinitely small hole is inserted at a point in the material domain. Schumacher...

...Wendong Huo; Chang Liu; Zongliang Du; Xudong Jiang; Zhenyu Liu; Xu Guo In the present article, an integrated paradigm for topology optimization on complex surfaces with arbitrary genus is proposed. The approach is constructed based on the two-dimensional (2D) Moving Morphable Component (MMC...

...Pai Liu; Xiaopeng Zhang; Yangjun Luo The topological design of structures to avoid vibration resonance for a certain external excitation frequency is often desired. This paper considers the topology optimization of freely vibrating bi-material structures with fixed/varying attached mass positions...

...Xiaojia Shelly Zhang; Eric de Sturler; Alexander Shapiro Practical engineering designs typically involve many load cases. For topology optimization with many deterministic load cases, a large number of linear systems of equations must be solved at each optimization step, leading to an enormous...
