论文摘要
我们提出了一种新算法来设计具有多物理环境中必需特性的轻质蜂窝材料。特别是，我们通过促进具有各向同性和各向异性行为在机械和热需求的各向异性行为的特征的单位细胞的设计上专注于热机械设置。提出的过程通过保留参考设计方法的所有良好属性，将微型算法推广到多物理框架。所得的布局表现出非标准的拓扑结构，其特征是非常清晰的轮廓，因此在制造前限制了后处理。将新的蜂窝材料与工程实践中的最新材料相提并论，从热力学特性角度来看，突出了新布局的良好性能，在某些情况下，这些性能优于合并的选择。
We present a new algorithm to design lightweight cellular materials with required properties in a multi-physics context. In particular, we focus on a thermo-mechanical setting, by promoting the design of unit cells characterized both by an isotropic and an anisotropic behaviour with respect to mechanical and thermal requirements. The proposed procedure generalizes microSIMPATY algorithm to a multi-physics framework, by preserving all the good properties of the reference design methodology. The resulting layouts exhibit non-standard topologies and are characterized by very sharp contours, thus limiting the post-processing before manufacturing. The new cellular materials are compared with the state-of-art in engineering practice in terms of thermo-mechanical properties, thus highlighting the good performance of the new layouts which, in some cases, outperform the consolidated choices.
