Auxetic behavior on demand: a three steps recipe for new designs

no code implementations • 29 Jan 2021 • Daniel Acuna, Francisco Gutiérrez, Alvaro S. Nunez, Gustavo Düring

Perfect auxetics are characterized by a Poisson's ratio $\nu=-1$ over a finite strain range and can be modeled as materials composed of rotating rigid units.

Critical yielding rheology: from externally deformed glasses to active systems

no code implementations • 29 Jan 2021 • Carlos Villarroel, Gustavo Düring

Here we use computer simulations to study the yielding transition under two different loading schemes: standard simple shear dynamics, and self-propelled, dense active systems.
