TL;DR: 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.

TL;DR: 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.

TL;DR: 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.

TL;DR: In this paper, a thermodynamically rigorous nonlinear elastic constitutive equation was derived for two-dimensional molybdenum disulfide, and the authors used first-principles density functional theory (DFT) calculations to predict the behavior of suspended monolayer MoS{}$ subjected to a spherical indenter load at finite strains in a multiple-length-scale finite element analysis model.

TL;DR: In this article, a thermodynamically rigorous continuum description of the elastic response is formulated by expanding the elastic strain energy density in a Taylor series in strain truncated after the fifth-order term.
