TL;DR: P pantographic metamaterials undergo very large deformations while remaining in the elastic regime, are very tough in resisting to damage phenomena, and exhibit robust macroscopic mechanical behavior with respect to minor changes in their microstructure and micromechanical properties.
Journal ArticleDOI
Homogenization à la Piola produces second gradient continuum models for linear pantographic lattices
TL;DR: In this paper, it was shown that the linearized homogenized model for a pantographic lattice must necessarily be a second gradient continuum, as defined in Germain (1973).
Journal ArticleDOI
Construction of micropolar continua from the asymptotic homogenization of beam lattices
TL;DR: In this article, the asymptotic homogenization of periodic beam lattices is performed in an algorithmic format, leading to a micropolar equivalent continuum, restricted to lattices endowed with a central symmetry, for which there is no coupling between stress and curvature.
Journal ArticleDOI
Equivalent mechanical properties of auxetic lattices from discrete homogenization
TL;DR: In this article, the authors analyzed the properties of the re-entrant and the rolling-up mechanism of a 2D periodical lattice and showed that the predicted homogenized properties depend on the slenderness of the beam.
Journal ArticleDOI
A micropolar anisotropic constitutive model of cancellous bone from discrete homogenization.
TL;DR: An anisotropic micropolar equivalent continuum model is constructed, the effective mechanical properties of which are identified, highlighting the regularizing effect of the Cosserat continuum in comparison to a classical elasticity continuum model.
