... Wrinkles in graphene with desirable morphology have practical significance for electronic applications. Here we carry out a systematic molecular dynamics study of the wrinkling instability of graphene on substrate-supported nanoparticles (NPs). At a large NP dispersion distance, a monolayer graphene...

...Zhao Qin; Markus J. Buehler for a wavy CNT-graphene system. It is seen that the loop period for this problem is only a function of the CNT diameter and that the radius of the loop at the maximum amplitude is a function of the CNT diameter as well as the applied strain. The diameter of the CNT...

... 2013 01 02 2013 08 04 2013 In situ low-voltage transmission electron microscopy (TEM) was performed to study the evolution of small Pt clusters on suspended graphene. Pt clusters, trapped by the edge of holes, generally take a stable shape of truncated octahedron for sizes ranging from...

... 2013 In this paper we attempt to answer two questions on graphene from a mechanic's viewpoint: why does this one-atom-thick monolayer have finite bending stiffness to ensure its stability? and what is its wrinkle mechanism? As for the first question, it is found that the repulsive residual...

... Huang. 31 01 2013 10 04 2013 13 04 2013 We explore here the structural stability and fracture of supported graphene sheets under pressure loadings normal to the sheets by performing molecular dynamics simulations. The results show that, in absence of defects, supported graphene...

... 27 02 2013 08 04 2013 Pressurized graphene bubbles have been observed in experiments, which can be used to determine the mechanical and adhesive properties of graphene. A nonlinear plate theory is adapted to describe the deformation of a graphene monolayer subject to lateral loads...

... Among the many potential two-dimensional carbon allotropes inspired by graphene, graphynes have received exceptional attention recently. Graphynes exhibit remarkable mechanical properties depending on their structure. The similar structure and two-dimensional nature of these materials yield many...

...K. Y. Volokh Failure of a single-atomic-layer graphene sheet is analyzed in plane tension under the varying biaxiality condition. The analysis is based on the combined use of continuum and molecular mechanics where the strain energy is expressed with the help of the Tersoff-Brenner atomistic...

...B. Yang; R. M. Rethinam; S. Mall Graphite at the nanoscale is modeled as a material system consisting of a stack of parallel plates buffered by an elastic material. While the plates represent individual graphene sheets, the buffer material models the Van der Waals interaction between the graphene...
