A new material property of graphene: the bending Poisson coefficient
Cesare Davini, Antonino Favata, Roberto Paroni
The in-plane infinitesimal deformations of graphene are well understood: they can be computed by solving the equilibrium problem for a sheet of isotropic elastic material with suit…
The Gaussian Stiffness of Graphene deduced from a Continuum Model based on Molecular Dynamics Potentials
Cesare Davini, Antonino Favata, Roberto Paroni
We consider a discrete model of a graphene sheet with atomic interactions governed by a harmonic approximation of the 2nd-generation Brenner potential that depends on bond lengths,…
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…
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 Beam Theory Consistent with Three-Dimensional Thermo-Elasticity
Antonino Favata
We propose a model for thermo-elastic beams, consistent with the theory of linear three-dimensional thermo-elasticity and deduced by a suitable version of the Principle of Virtual…
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…
