On the compact wave dynamics of tensegrity beams in multiple dimensions
Andrea Micheletti, Giuseppe Ruscica, Fernando Fraternali
This work presents a numerical investigation on the nonlinear wave dynamics of tensegrity beams in 1D, 2D and 3D arrangements. The simulation of impact loading on a chain of tenseg…
A 2D metamaterial with auxetic out-of-plane behavior and non-auxetic in-plane behavior
Cesare Davini, Antonino Favata, Andrea Micheletti +1
Customarily, in-plane auxeticity and synclastic bending behavior (i.e. out-of-plane auxeticity) are not independent, being the latter a manifestation of the former. Basically, this…
How graphene flexes and stretches under concomitant bending couples and tractions
Antonino Favata, Andrea Micheletti, Paolo Podio-Guidugli +1
We propose a geometrically and physically nonlinear discrete mechanical model of graphene that assigns an energetic cost to changes in bond lengths, bond angles, and dihedral angle…
An analytical benchmark for MD codes: testing LAMMPS on the 2nd generation Brenner potential
Antonino Favata, Andrea Micheletti, Seunghwa Ryu +1
An analytical benchmark is proposed for graphene and carbon nanotubes, that may serve to test whatsoever molecular dynamics code implemented with REBO potentials. By exploiting the…
A Class of Minimal Generically Universally Rigid Frameworks
Scott D. Kelly, Andrea Micheletti
Following a review of related results in rigidity theory, we provide a construction to obtain generically universally rigid frameworks with the minimum number of edges, for any giv…
Geometry and Self-Stress of Single-Wall Carbon Nanotubes and Graphene via a Discrete Model Based on a 2nd-Generation REBO Potential
Antonino Favata, Andrea Micheletti, Paolo Podio-Guidugli +1
The main purpose of this paper is to evaluate the self-stress state of single-wall carbon nanotubes (CNTs) and flat graphene strips (FGSs) in their natural equilibrium state, that…
A Nonlinear Theory of Prestressed Elastic Stick-and-Spring Structures
Antonino Favata, Andrea Micheletti, Paolo Podio-Guidugli
The discrete modeling of a large class of mechanical structures can be based on a stick-and-spring concept. We here present a stick-and-spring theory with potential application to…
On shear and torsion factors in the theory of linearly elastic rods
Antonino Favata, Andrea Micheletti, Paolo Podio-Guidugli
Lower bounds for the factors entering the standard notions of shear and torsion stiffness for a linearly elastic rod are established in a new and simple way. The proofs are based o…
