摘要

封面图片展示了通过增材制造制造的具有渐变形状变形的可重新进入的蜂窝超材料。通过自适应地改变基于s型的变形函数的几何参数来实现形状变形，从而实现线性形变行为。分析了封面图片中突出显示的六种具有不同变形参数的单元设计，以实现负泊松比最小偏差的线性辅助。实验结果表明，泊松比的相对变化减少了70%，同时保持了较高的幅度。更多的细节可以在Keun Park和同事的文章2400889中找到。

Shape Morphing of Re-Entrant Honeycomb Metamaterials for Linear Auxetic Behaviors

Re-Entrant Honeycomb Metamaterials

The cover image illustrates a re-entrant honeycomb metamaterial with graded shape morphing, fabricated via additive manufacturing. The shape morphing is achieved by adaptively changing the geometric parameters of sigmoid-based morphing functions to enable linear auxetic behaviors. Six cell designs with different morphing parameters, highlighted in the cover image, are analyzed to achieve linear auxetics with minimal deviations in the negative Poisson’s ratio. The experimental results reveal a 70% reduction in the relative variation of Poisson’s ratio, while maintaining a high magnitude. Further details can be found in article 2400889 by Keun Park and co-workers.
