© 2018 Elsevier B.V. This paper proposes a new multiscale topology optimization method for the design of porous composites composed of the multi-domain material microstructures considering three design elements: the topology of the macrostructure, th...

© 2018 Elsevier Ltd In conventional parametric level set methods, the compactly supported radial basis functions (CSRBF) are used to approximate the level set function due to their unique properties, such as the sparsity of the interpolation matrix. ...

Copyright © 2017 John Wiley & Sons, Ltd. In this paper, a level-set-based method is presented to deal with the multi-material topology optimization of compliant mechanisms with stress constraints. A novel stress-based multi-material topology optimiza...

© 2018 Elsevier B.V. For structure–acousticsystem with uncertainties, the interval model, the random model and the hybrid uncertain model have been introduced. In the interval model and the random model, the uncertain parameters are described as eith...

© 2017 Elsevier B.V. The application of auxetic composites in practice often relies on a compromise between properties as auxetics are mostly too porous (not dense enough or not stiff enough) to bear structural loads. Hence, the focus of this paper i...

Purpose - The sampling methods (or design of experiments) which have large influence on the performance of the surrogate model will be mainly studied. To improve the adaptability of modelling, a new sequential sampling method termed as sequential Che...

© 2017 Elsevier B.V. This paper proposes a level set-based robust topology optimization (RTO) method for computational design of metamaterials under hybrid uncertainties, e.g. auxetics with negative Poisson's ratio, where the Young's modulus of the s...

© 2016 Elsevier B.V. This paper proposes a hierarchical multi-scale topology optimization method for the design of integrated materials and structures by taking advantage of both cellular composites and functionally graded materials. The topology opt...
