In this paper, systematic molecular dynamics simulations were employed to study
dislocation-graphene interactions in Cu/graphene systems using two carefully selected …

Interatomic potentials based on neural-network machine learning method have attracted
considerable attention in recent years owing to their outstanding ability to balance the …

Despite a wide range of current and potential applications, one primary concern of brittle
materials is their sudden and swift collapse. This failure phenomenon exhibits an inability of …

A promising materials engineering method for improving the strength of crystalline materials
is to add obstacles to dislocation motion that induce interface hardening (IH) or precipitate …

Graphene nanosheets (GNS) can enhance the strength and ductility of metal-based
composites as they can obstruct the propagation of dislocations. The present article employs …

Molecular mechanics models like the molecular structural mechanics (MSM) model have
been proven to be a valuable tool for the investigation of carbon nanotubes. This class of …

Understanding the interfacial behavior of graphene-polymer nanocomposite is a long-
standing endeavor to gain deep insight into the mechanical properties of engineered …

Solids exhibit transverse shrinkage when they are stretched, except auxetics that abnormally
demonstrate lateral expansion instead. Graphene possesses the unique normal-auxeticity …

This paper presents the implication of crystallographic orientation on toughness and ideal
strength in graphene under lattice symmetry-preserving and symmetry-breaking …

The macroscopic behaviors of materials are determined by interactions that occur at multiple
lengths and time scales. Depending on the application, describing, predicting, and …
