A new block-based approach for the analysis of damage in masonries undergoing large deformations
(Springer, 2023)
Acceso restringido
A new block-based elasto-damage model for describing masonry structures has been recently proposed (Tran et al. in Mech Res Commun 118:103802, 2021), where the used constitutive elastic and damage behavioral laws were ...
Investigating the effect of nanovoid inelastic surface stress and the austenite–martensite interface inelastic stress on the martensitic growth at the nanovoid surface
(Springer, 2023)
Acceso restringido
In this paper, the effect of nanovoid inelastic surface stress and austenite (A)–martensite (M) interface inelastic stress on the martensitic growth at the nanovoid surface is investigated. Within the phase field approach ...
A beam model for duoskelion structures derived by asymptotic homogenization and its application to axial loading problems
(Elsevier Ltd., 2023)
Acceso restringido
Duoskelion 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 ...
Nonlinear dynamics of origami metamaterials: energetic discrete approach accounting for bending and in-plane deformation of facets
(Springer, 2023)
Acceso restringido
In 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 ...
Coupled phase field and nonlocal integral elasticity analysis of stress-induced martensitic transformations at the nanoscale: boundary effects, limitations and contradictions
(Springer, 2023)
Acceso restringido
In 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 ...
Maximum mechano-damage power release-based phase-field modeling of mass diffusion in damaging deformable solids
(Springer, 2022)
Acceso restringido
We formulate in three space dimensions a phase-field theory of mass diffusion in a damaging deformable solid matrix without making use of thermal quantities. The approach relies on three fundamental postulates: the diffusing ...
Characterization of the Shells in Layer-By-Layer Nanofunctionalized Particles: A Computational Study
(Frontiers Media S.A., 2022)
Acceso abierto
Drug 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 ...
In-plane dynamic buckling of duoskelion beam-like structures: discrete modeling and numerical results
(SAGE Publications Inc., 2022)
Acceso restringido
In 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 waves in pantographic beams induced by transverse impulses
(Elsevier, 2022)
Acceso restringido
We 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 ...
Solution of a paradox related to the rigid bar pull-out problem in standard elasticity
(Elsevier, 2022)
Acceso restringido
This paper aims at modeling pull-out tests of a reinforcement bar from a concrete matrix. The considered system is an elastic cylinder, within which is embedded a rigid bar placed along the central axis. The pull-out test ...
