“…Similar effect of GO dispersion on the elastic modulus of electrospun gelatin nanofibers is reported by Jalaja et al 27 Secondly, the covalent bonds created between polymers and GO-COOH can alter the structure of graphene that might impact the global nanomechanical properties of nanofibrous scaffolds. 66 Then, it is well established that the spatial orientation of the nanofillers within the polymer-based material has a vital role on its collective mechanical properties. The materials with random/misoriented graphene-nanofiller layers present a low Young's modulus as compared to fully aligned ones.…”

“…Polymer nanocomposites embedded with nanoparticles such as CNTs, graphene and their derivatives, nanoclays, and silica nanoparticles have attracted a large amount of attention to achieve more improved thermomechanical properties than conventional composites . Among all others, CNTs have been emerged as the ideal candidates for multifarious applications due to their remarkable thermoelastic and physical properties.…”

This article deals with the prediction of thermomechanical properties of fiber reinforced composites using several micromechanics models. These include strength of material approach, Halpin-Tsai equations, multi-phase mechanics of materials approaches, multiphase Mori-Tanaka models, composite cylindrical assemblage model, Voigt-Reuss models, modified mixture rule, Cox model, effective medium approach and method of cells. Several composite systems reinforced with short and long, aligned, random and wavy reinforcements were considered. In addition, different aspects such as fiber-matrix interphase, fiber-matrix interfacial thermal resistance, fiber geometry, and multiple types of reinforcements were considered to model the composites systems. The current study also presents some important preliminary concepts and application of developed micromechanics models to advanced nanocomposites such as carbon nanotube reinforced composite. Main contribution of the current work is the investigation of several analytical micromechanical models, while most of the existing studies on the subject deal with only one or two approaches considering few aspects.

“…Further, [9] studied the buckling strain of the variants of Gr with varying in-plane compressive strains, see also [10]. Moreover, [11,12] focused on exploring the mechanical characteristics of the material with respect to surface functionalization. They concluded even stronger bond between functionalized Gr and mechanical properties, see also [13][14][15] for more specifics.…”

This article fundamentally aims at the comparative study of thermo-mechanical characters of Gr/Ag and Gr/Cu nano-composites. For demonstration purposes, three dimensions that is, (1 0 0), (1 1 0) and (1 1 1), of the metals attached with single layer Graphene sheet are considered. The study is facilitated by the adaptation of the molecular dynamic simulations of the soft LAMMPS to mimic the broad range of experimental environment. The attributes of each structure and their orientations are elaborated over wide range of experimental states, encompassing temperature ranging from 300 K to 1500 K, to assess the melting behavior. The thermal and structural properties are explored by employing mean square displacement (MSD) and radial distribution function (RDF). Furthermore, the mechanical characters are elaborated along both arm-chair and zigzag directions. The findings are supported by producing relevant graphical displays of stress-strain curves and generating extravagant depictions of various dislocations with the application of visual molecular dynamics (VMD) tool. On the basis of intense and careful computational investigations, we witnessed that the Gr/Cu (1 1 1) orientation produced most profound melting characteristics along with distinctive strengthening and fracture mechanism. These outcomes are consistent in comparison of both Gr/Metals layered structures and also with respect to all considered metallic orientations. The findings are discussed thoroughly in a well-structured and synchronized fashion throughout the article.
