Elastic properties of hydrogenated graphene
Emiliano Cadelano, Pier Luca Palla, Stefano Giordano +1
There exist three conformers of hydrogenated graphene, referred to as chair-, boat-, or washboard-graphane. These systems have a perfect two-dimensional periodicity mapped onto the…
A lattice model describing scale effects in nonlinear elasticity of nano-inhomogeneities
Pier Luca Palla, Stefano Giordano, Luciano Colombo
We present a procedure to map the constitutive laws of elasticity (both in the linear and nonlinear regime) onto a discrete atomic lattice and we apply the resulting elastic lattic…
Interplay between bending and stretching in carbon nanoribbons
Emiliano Cadelano, Stefano Giordano, Luciano Colombo
We investigate the bending properties of carbon nanoribbons by combining continuum elasticity theory and tight-binding atomistic simulations. First, we develop a complete analysis…
Nonlinear elasticity of monolayer graphene
Emiliano Cadelano, Pier Luca Palla, Stefano Giordano +1
By combining continuum elasticity theory and tight-binding atomistic simulations, we work out the constitutive nonlinear stress-strain relation for graphene stretching elasticity a…
