The mechanical properties of monolayer graphene including Young’s modulus and fracture strength have been investigated by numerical simulations such as molecular dynamics. The Young’s modulus of few-layer graphene was experimentally investigated with force-displacement measurements by atomic force microscopy...
where τc is the ISS, E is the Young’s modulus of graphene that is assumed as 350 N m−1, εc is the maximum strain in the top graphene layer, and L is the lateral size of the top layer along the tensile direction. A series of experiments were conducted using BLG with dif...
As a result, the tensile strength of fibers prepared by melt spinning of the Nylon-graphene composite were increased 2.1-fold and the Young’s modulus 2.4-fold with a graphene loading of only 0.1%.91 The availability of stable dispersions of CCG particularly in organic solvents has led to ...

The improved load transfer between the GO sheets gives rise to a maximum of 200 and 400% increases in Young's modulus and tensile strength of GO papers. The intercalation of chlorine between the GO layers alters the properties of GO papers in two ways by forming ionic Cl– and covalent C...
Due to the edge effects, the initial Young's modulus of graphene nanoribbons under infinitesimal strain varies with the edge chirality and the ribbon width. Furthermore, it is found that the nominal strain to fracture is considerably lower for armchair graphene nanoribbons than for zigzag ribbons....
where API is the area under the force–displacement curve, E is the Young’s modulus, and ν is the Poisson’s ratio. The crack extension (Δa) is calculated by Eq. (3) [44]: $$a_{n} = a_{n - 1} + \frac{{W - a_{n - 1} }}{2}\frac{{C_{n} - C_{n - 1} }...
Finite element simulations were performed in ABAQUS software. A circular monolayer graphene sheet with a diameter of 1.2 μm was modeled as a linear elastic isotropic plate using the four-node shell (S4R) element. The following parameters were adopted: Young’s modulusE = 1,000 GPa...
