Identification of a geometrically nonlinear micromorphic continuum via granular micromechanics
(SpringerCH, 2021)
Describing the emerging macro-scale behavior by accounting for the micro-scale phenomena calls for microstructure-informed continuum models accounting properly for the deformation mechanisms identifiable at the micro-scale. ...
Fluid dynamics of air in a packed bed: velocity profiles and the continuum model assumption
(Brazilian Society of Chemical Engineering, 1999-12-01)
Air flow through packed beds was analyzed experimentally under conditions ranging from those that reinforce the effect of the wall on the void fraction to those that minimize it. The packing was spherical particles, with ...

Two-dimensional modeling of material failure in reinforced concrete by means of a continuum strong discontinuity approach
(Elsevier B.V. Sa, 2008-01-01)
The paper presents a new methodology to model material failure, in two-dimensional reinforced concrete members, using the Continuum Strong Discontinuity Approach (CSDA). The mixture theory is used as the methodological ...

Two-Dimensional Analysis of Size Effects in Strain-Gradient Granular Solids with Damage-Induced Anisotropy Evolution
(American Society of Civil Engineers (ASCE)US, 2021)
We analyze in two dimensions the mechanical behavior of materials with granular microstructures modeled by means of a variationally formulated strain-gradient continuum approach based on micromechanics and show that it can ...
