A continuum model for GO membranes is developed in this study. The model is built representing the membrane as a two-dimensional, heterogeneous, two-phase continuum and the constitutive behavior of each phase (graphitic or oxidized) is built based on DFTB simulations of representative patches. A hyper-elastic continuum model is employed for the graphene areas, while a continuum damage model is more adequate for representing the behavior of oxidized regions. A finite element implementation for GO membranes subjected to degradation and failure is then implemented and, to avoid localization instabilities and spurious mesh sensitivity, a simple crack band model is adopted. The developed implementation is then used to investigate the existence of GO nano-representative volume elements.

Limiting Value

The dependence of electrical conductivity on the electric field strength and relaxation processes in the proton solid electrolyte RbH₂PO₄ are investigated. With increasing electric field strength, the electrolyte conductivity increases in an attempt to the limiting value. The relative increase in conductivity and relaxation time with increasing temperature increase and reaches 208% at 600 K. The relaxation time is of the order of 104 s.

Fixed Boundary Condition

The objective of this paper is to study the low frequency acoustic vibration of Te2 cluster and CdSeTe nanoparticle embedded in borosilicate glass matrix. Lamb’s model is used to predict the occurrence of various mode to support the experimental observations by considering the elastic continuum model and fixed boundary condition. The presence of medium significantly affects the phonon peaks and results into the broadening of the modes. The linewidth is found to depend inversely on the size, similar to that reported experimentally.

Good Agreement

By analogy with the elastic theory of solid shells1 and fluid membranes,2 it has been suggested that fullerenes, at least large ones, might somehow resemble the classic elastic continuum, as indicated by Schnur.3 Some related works dealt with nanotubes do show positive evidence for this suggestion.4 Here we propose an elastic continuum model appropriate to graphite-like networks. Applying it to various shapes of fullerenes, such as spheres, tubes, tori, and minimal surfaces, we found good agreement between this model and previous numerical results given by approaches of ab initio or empirical potential. Furthermore, this model enables one to understand the puzzling phenomena such as why Schwarzite P216 and Schwarzite D216 have nearly identical bending energies while their geometric forms are very different (see Fig. 1). The prospect of this model is also discussed.
