A beam model for duoskelion structures derived by asymptotic homogenization and its application to axial loading problems
Barchiesi, Emilio; dell'Isola, Francesco; Seppecher, Pierre; Turco, Emilio (Elsevier Ltd., 2023)Acceso restringidoDuoskelion structures have been recently introduced by Barchiesi et al. (2021) as a proof-of-concept motif for a new class of metamaterials. The properties of these periodic beam-like chiral structural elements have been ... -
A block-based variational elasto-damage model for masonry analysis inspired from granular micromechanics: Preliminary study
Tran, C. A.; Barchiesi, Emilio; Placidi, L.; León Trujillo, Francisco James (Elsevier, 2021)Acceso restringidoWe develop a new block-based elasto-damage model for describing masonry structures.

(Frontiers Media S.A., 2022)Acceso abiertoDrug delivery carriers are considered an encouraging approach for the localized treatment of disease with minimum effect on the surrounding tissue. Particularly, layer-by-layer releasing particles have gained increasing ... -
Coupled phase field and nonlocal integral elasticity analysis of stress-induced martensitic transformations at the nanoscale: boundary effects, limitations and contradictions
Danesh, Hooman; Javanbakht, Mahdi; Barchiesi, Emilio; Hamila, Nahiene (Springer, 2023)Acceso restringidoIn this paper, the coupled phase field and local/nonlocal integral elasticity theories are used for stress-induced martensitic phase transformations (MPTs) at the nanoscale to investigate the limitations and contradictions ... -
Gastropopulism: a sociosemiotic analysis of politicians posing as “the everyday man” via food posts on social media
Misra, A.; Placidi, L.; dell'Isola, F.; Barchiesi, Emilio (Springer, 2021)Acceso abiertoDescribing 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. ... -
Identification of a geometrically nonlinear micromorphic continuum via granular micromechanics

Specifically, the analysis is carried out in large displacements ... -
In-plane dynamic buckling of duoskelion beam-like structures: discrete modeling and numerical results
Turco, Emilio; Barchiesi, Emilio; dell’Isola, Francesco (SAGE Publications Inc., 2022)Acceso restringidoIn this contribution, a previously introduced discrete model for studying the statics of duoskelion beam-like structures is extended to dynamics. The results of numerical simulations performed using such an extended model ... -
