A Survey of Interlayer Interaction Models for Graphene and Other 2D Materials

Advanced Materials Interfaces, EarlyView.
Van der Waals interactions arising from electronic polarization at atomically close interfaces generate corrugated interlayer energy landscapes that govern normal and tangential tractions. This review presents an overview of quantum, atomistic, analytical, and continuum modeling approaches, highlighting their roles across length scales in capturing ...

Finite element modelling of the instability in rapid fracture of graphene

, 2015
A finite element model of graphene strip is developed to predict the instability of dynamic fracture, in which the C-C bonds are represented by Timoshenko beam elements, and the constitutive relation of beam is derived from the atomic potential.

Fracture mechanics of plate debonding

The study has shown that the phenomena of plate debonding can be studied by means of a fracture-mechanics approach, which obviates the need for a finite element analysis which would have dubious validity in the presence of infinite stress concentrations ...
