Measurement of the Elastic Properties and Intrinsic Strength of Monolayer Graphene
Graphene is established as the strongest material ever measured, and atomically perfect nanoscale materials can be mechanically tested to deformations well beyond the linear regime.
High-Strength Chemical-Vapor–Deposited Graphene and Grain Boundaries
It is shown that the elastic stiffness of CVD-graphene is identical to that of pristine graphene if postprocessing steps avoid damage or rippling, and its strength is only slightly reduced despite the existence of grain boundaries.

Nonlinear elastic behavior of graphene: Ab initio calculations to continuum description
The nonlinear in-plane elastic properties of graphene are calculated using density-functional theory. A thermodynamically rigorous continuum description of the elastic response is formulated by…
Strengthening effect of single-atomic-layer graphene in metal-graphene nanolayered composites.
A new material design in the form of a nanolayered composite consisting of alternating layers of metal (copper or nickel) and monolayer graphene that has ultra-high strengths of 1.5 and 4.0 GPa indicates the effectiveness of graphene in blocking dislocation propagation across the metal-graphene interface.
Elastic and frictional properties of graphene
We describe studies of the elastic properties and frictional characteristics of graphene samples of varying thickness using an atomic force microscope. For tensile testing, graphene is suspended over…
