Identification of a geometrically nonlinear micromorphic continuum via granular micromechanics
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 ... -
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 ... -
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 ... -
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 ...
