Stefania Donescu, Veturia Chiroiu, Ligia Munteanu. On the Young' s modulus of a auxetic composite structure. Mechanics Research Communications, vol 36, pp. 294-301, 2009.

Abstract: In this paper, the behavior of auxetic composites is interpreted in the light of Cosserat elasticity which admits degrees of freedom not present in the classical elasticity: The rotation
of points in the material, and a couple per unit area or the couple stress. The prediction of the Young’s modulus is developed for a laminated periodic material made up of alternating
aluminum and auxetic material, by using the Bécus homogenization technique.

Keywords: Auxetic material,Cosserat elasticity, Young's modulus, Negative Poisson ratio, Becus homogenization technique
