A talk will be given by

     Stefanie Hahmann

and is entitled:

     'Geometric Construction of Auxetic Metamaterials'

Abstract:

     This talk is devoted to a category of metamaterials called auxetics,
     identified by their negative Poisson's ratio. Our work consists in
     exploring geometrical strategies to generate irregular auxetic 
structures.
     More precisely we seek to reduce the Poisson's ratio 𝜈, by pruning an
     irregular network based solely on geometric criteria. We introduce a
     strategy combining a pure geometric pruning algorithm followed by a
     physics-based testing phase to determine the resulting Poisson's ratio
     of our structures. We propose an algorithm that generates sets of 
irregular
     auxetic networks. Our contributions include geometrical 
characterization
     of auxetic networks, development of a pruning strategy, generation of
     auxetic networks with low Poisson's ratio, as well as validation of our
     approach. We provide statistical validation of our approach on large
     sets of irregular networks, and we additionally laser-cut auxetic 
networks
     in sheets of rubber. The findings reported here show that it is 
possible
     to reduce the Poisson's ratio by geometric pruning, and that we can
     generate irregular auxetic networks at lower processing times than a
     physics-based approach.
