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 ... -
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 ... -
Kinematically triggered nonlinear vibrations of Hencky-type pantographic sheets
Turco, Emilio; Barchiesi, Emilio (Mathematical Science Publishers, 2021)Acceso restringidoPantographic 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 ... -
Nonlinear dynamics of origami metamaterials: energetic discrete approach accounting for bending and in-plane deformation of facets
Turco, Emilio; Barchiesi, Emilio; dell’Isola, Francesco (Springer, 2023)Acceso restringidoIn this paper, we start the analysis of the nonlinear dynamics of structural elements having an origami-type microstructure and micro-kinematics, also known as origami metamaterials. We use a finite-dimensional Lagrangian ... -
Nonlinear waves in pantographic beams induced by transverse impulses
Turco, Emilio; Barchiesi, Emilio; Ciallella, Alessandro; dell’Isola, Francesco (Elsevier, 2022)Acceso restringidoWe present and discuss the results of some numerical simulations dealing with wave motion in one-dimensional pantographic media, also known as pantographic beams. Specifically, the analysis is carried out in large displacements ... -
Validation of a Hemi-Variational Block-Based Approach to the Modelling of Common In-plane Failures in Masonry Structures
Torres Espino, José Manuel; Espinoza Sandoval, Jaime Heman; Tran, Chuong Anthony; Fedele, Roberto; Turco, Emilio; dell’Isola, Francesco; Placidi, Luca; Misra, Anil; León Trujillo, Francisco James; Barchiesi, Emilio (Springer, 2023)Acceso restringidoNumerical simulations of several planar failure modes of masonry structures are presented, based on the model and solving code from a recent hemivariational block-based model inspired from granular micromechanics (Tran et ...
