Effective properties of a new auxetic triangular lattice: an analytical approach
In this article we propose a new auxetic periodic lattice with negative Poisson's ratio which tends to the limit ν=-1 under particular conditions. We have studied its generation and kinematic, and we give a full description of the mechanical properties of this innovative model. Calibrating th...

| description | In this article we propose a new auxetic periodic lattice with negative Poisson's ratio which tends to
the limit ν=-1 under particular conditions. We have studied its generation and kinematic, and we give a full
description of the mechanical properties of this innovative model. Calibrating the geometrical configuration of
the lattice and the mechanical properties of the constituent material we are able to have a Poisson's ratio which
is arbitrarily close to -1. |
