HEXAGONAL BORON NITRIDE NANOSTRUCTURES: A NANOSCALE MECHANICAL MODELING

摘要

The paper deals with a numerical model for hexagonal boron nitride nanostructures. The model is developed in finite kinematics and takes into account binary, ternary and quaternary atomic interactions, described through the UFF potential with an extit{ad-hoc} set of parameters. Once validated with respect to extit{ab-initio} results of the tensile failure of boron nitride sheets under periodic conditions, the model is used to study the response of a sheet of finite size under traction, compression and shear.
