In the present paper a two dimensional plate, made by structural straight elements and showing an auxetic behaviour, is considered. Theoretical, experimental and numerical analyses for the characterisation of its mechanical properties are presented and compared. The main geometrical parameters of an elementary cell affecting the deformation behaviour are highlighted, with emphasis to the negative values of the Poisson’s ratio.

Abstract
In the present paper a two dimensional plate, made by structural straight elements and showing an auxetic behaviour, is considered. Theoretical, experimental and numerical analyses for the characterisation of its mechanical properties are presented and compared. The main geometrical parameters of an elementary cell affecting the deformation behaviour are highlighted, with emphasis to the negative values of the Poisson’s ratio.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
