论文摘要
我们提出了一种用于设计不同晶格材料之间连接区域的新算法。我们在狭窄的变形区域上解决了Stokes型拓扑优化问题，以平稳连接两个不同的单位细胞。提出的程序证明是有效的，并提供了材料的局部重新设计，从而导致对原始晶格的机械行为进行了非常温和的修改。根据最终布局对不同参数的敏感性评估算法的鲁棒性。笛卡尔和非 - 非牙龈变形区域的病例均已成功研究。
We present a new algorithm for the design of the connection region between different lattice materials. We solve a Stokes-type topology optimization problem on a narrow morphing region to smoothly connect two different unit cells. The proposed procedure turns out to be effective and provides a local re-design of the materials, leading to a very mild modification of the mechanical behaviour characterizing the original lattices. The robustness of the algorithm is assessed in terms of sensitivity of the final layout to different parameters. Both the cases of Cartesian and non-Cartesian morphing regions are successfully investigated.
