Effective properties of a new auxetic triangular lattice:an analytical approach
Journal Title: Frattura ed Integrità Strutturale - Year 2014, Vol 8, Issue 29
Abstract
In this article we propose a new auxetic periodic lattice with negative Poisson's ratio which tends tothe limit ν=-1 under particular conditions. We have studied its generation and kinematic, and we give a fulldescription of the mechanical properties of this innovative model. Calibrating the geometrical configuration ofthe lattice and the mechanical properties of the constituent material we are able to have a Poisson's ratio whichis arbitrarily close to -1.
