An analytic study on the properties of solitary waves traveling on tensegrity-like lattices
Ada Amendola
This paper develops an analytic study on the existence and properties of solitary waves on 1D chains of lumped masses and nonlinear springs, which exhibit a mechanical response sim…
Limit analysis of strut nets
Ada Amendola, Antonio Fortunato, Fernando Fraternali +3
Truss structures composed of members that work exclusively in tension or in compression appear in several problems of science and engineering, e.g., in the study of the resisting m…
The obstacle problem in masonry structures and cable nets
Ada Amendola, Ornella Mattei, Graeme W. Milton +1
We consider the problem of finding a net that supports prescribed forces applied at prescribed points, yet avoids certain obstacles, with all the elements of the net under compress…
Effect of prestress on phononic band gaps induced by inertial amplification
M. Miniaci, M. Mazzotti, A. Amendola +1
We report about the effect of an applied external mechanical load on a periodic structure exhibiting band gaps induced by inertial amplification mechanism. If compared to the cases…
Innovative seismic isolation devices based on lattice materials: A review
F. Fraternali, A. Amendola, G. Benzoni
This paper reviews recent literature results on the mechanics of structures formed by layers of pentamode lattices alternating with stiffening plates, which can be effectively empl…
Mechanical modeling of innovative metamaterials alternating pentamode lattices and confinement plates
F. Fraternali, A. Amendola
This study examines the mechanical behavior of a novel class of mechanical metamaterials alternating pentamode lattices and stiffening plates. The unit cell of such lattices consis…
Bending dominated response of layered mechanical metamaterials alternating pentamode lattices and confinement plates
A. Amendola, G. Carpentieri, L. Feo +1
A numerical study on the elastic response of single- and multi-layer systems formed by alternating pentamode lattices and stiffening plates is presented. Finite element simulations…
Incremental auxetic response of composite lattices under isotropic prestress
Ada Amendola, Fernando Fraternali
This work studies the constitutive response of two- and three-dimensional lattice materials subject to isotropic prestress. The unit cell of the examined lattices is formed by an a…
Mathematical modeling of a Cosserat method in finite-strain holonomic plasticity
Thomas Blesgen, Ada Amendola
This article deals with the mathematical derivation and the validation over benchmark examples of a numerical method for the solution of a finite-strain holonomic (rate-independent…
On a modified Becker-Doering model for two-phase materials
Thomas Blesgen, Ada Amendola, Fernando Fraternali
This work reconsiders the Becker-Doering model for nucleation under isothermal conditions in the presence of phase transitions. Based on thermodynamic principles a modified model i…
Accordion-like metamaterials with tunable ultra-wide low-frequency band gaps
Anastasiia O. Krushynska, Ada Amendola, Federico Bosia +3
We study lightweight, elastic metamaterials consisting of tensegrity-inspired prisms, which present wide, low-frequency band gaps. For their realization, we alternate tensegrity el…
Tuning frequency band gaps of tensegrity metamaterials with local and global prestress
Ada Amendola, Anastasiia Krushynska, Chiara Daraio +2
This work studies the acoustic band structure of tensegrity metamaterials, and the possibility to tune the dispersion relation of such systems by playing with local and global pres…
On the additive manufacturing, post-tensioning and testing of bi-material tensegrity structures
A. Amendola, E. Hernandez-Nava, R. Goodall +3
An investigation on the additive manufacturing and the experimental testing of 3D models of tensegrity prisms and columns is presented. An electron beam melting facility (Arcam EBM…
Experimental investigation of the softening-stiffening response of tensegrity prisms under compressive loading
Ada Amendola, Fernando Fraternali, Gerardo Carpentieri +2
The present paper is concerned with the formulation of new assembly methods of bi-material tensegrity prisms, and the experimental characterization of the compressive response of s…

Fernando Fraternali, Gerardo Carpentieri, Ada Amendola
We study the geometrically nonlinear behavior of uniformly compressed tensegrity prisms, through fully elastic and rigid--elastic models. The presented models predict a variety of…
Continuum limits of bistable spring models of carbon nanotube arrays accounting for material damage
T. Blesgen, F. Fraternali, J. R. Raney +2
Using chains of bistable springs, a model is derived to investigate the plastic behavior of carbon nanotube arrays with damage. We study the preconditioning effect due to the loadi…
