Homogenization of heterogeneous Cauchy-elastic materials leads to Mindlin second-gradient elasticity
Through a second-order homogenization procedure, the explicit relation is obtained between the non-local parameters of a second gradient elastic ma- terial and the microstructure of a composite material. This result is instru- mental for the definition of higher-order models, to be used for the …

FEMxDEM double scale approach with second gradient regularization applied to granular materials modeling
… using an OpenMP paradigm. At the macro level, a second gradient constitutive relation is implemented in order to enrich the first gradient Cauchy relation bringing mesh-independency to the model. The aforementioned improvements make the FEMxDEM approach competitive with classical FEM models in …

CHARACTERISATION OF THE MECHANICAL BEHAVIOUR OF NETWORKS AND WOVEN FABRICS WITH A DISCRETE HOMOGENIZATION MODEL
… in which the fibres are not orthogonal. A first gradient medium is usually obtained but, in some cases, the homogenization procedure itself indicates that a higher order continuum is better fit to represent the deformation of the micro-structure. Special results were obtained for the case of …
