Abstract
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.
