On the evaluation of the young’s modulus for a laminated periodic composite structure based on auxetic materials

Abstract

In this paper, the dynamic behavior of auxetic materials are interpreted in the light of Cosserat elasticity which admits degrees of freedom not present in classical elasticity: the rotation of points in the material, and a couple per unit area or the couple stress. The prediction of the Young’modulus is developed for a composite made up from aluminum and an auxetic material.
