Identification of a geometrically nonlinear micromorphic continuum via granular micromechanics
(Springer, 2021)
Acceso abierto
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. ...
Kinematically triggered nonlinear vibrations of Hencky-type pantographic sheets
(Mathematical Science Publishers, 2021)
Acceso restringido
Pantographic metamaterials are receiving increasing attention from the scientific community working in theoretical and numerical mechanics. Nevertheless, dynamic analysis of pantographic sheets in the large deformation ...
Two-Dimensional Analysis of Size Effects in Strain-Gradient Granular Solids with Damage-Induced Anisotropy Evolution
(American Society of Civil Engineers (ASCE), 2021)
Acceso restringido
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 ...
A block-based variational elasto-damage model for masonry analysis inspired from granular micromechanics: Preliminary study
(Elsevier, 2021)
Acceso restringido
We develop a new block-based elasto-damage model for describing masonry structures. The constitutive elastic and damage behavioural laws used within the proposed approach are inspired from those employed in the recent ...
