“…Therefore, it is possible to more accurately analyze the various physical behaviors and phenomena of polymer nanocomposites based on this analysis. Analysis of the effect of parameters related to the distribution of fillers, such as dispersion [122,[131][132][133][134][135][136][137][138][139][140][141], agglomeration [123,142,143], clustering [144], and volume concentration effect [145] on the physical properties of nanocomposites, as a key factor when inserting nano filler into polymer nanocomposites, is being carried out. The effect of the interphase generated around the filler can be properly interpreted through the multiscale analysis methodology.…”

Ever since several formations of polymer-based nanocomposites were reported, research on their modeling, characterization, and computerized analysis methodology has been extensively investigated to become a major academic field of advanced material science and technology. This paper mainly summarizes the multiscale computational analysis methodology for polymer nanocomposites. We also introduce various computational modeling approaches to characterizing the physical behavior of polymer nanocomposites, which are the molecular dynamics approach, and the continuum approach. Based on the various computational analyses, we summarize how the material properties and phenomenological behaviors of polymer nanocomposites were analyzed.

“…Spanos et al 89 employed a multiscale homogenization approach to link the structural variability between the nano and micro scales considering the local constitutive behavior. A combination of MD simulations, continuum elasticity, and FEM was used by Montazeri et al 90 to evaluate the effect of CNT orientation on the shear modulus of SWCNT/ polymer nanocomposites. Ayatollahi et al 91 used the multiscale method to study the respone of SWCNT/ polymer nanocomposites under tensile, bending and torsional loadings.…”

In this paper, the elastic properties of functionally graded materials reinforced by single-walled carbon nanotubes are studied. Three different matrices, including steel-silicon, iron-alumina and alumina-zirconia are considered. Besides, the effects of nanotube length, radius and volume fraction on the Young’s modulus of functionally graded matrices reinforced by single-walled carbon nanotubes are investigated. It is observed that short nanotubes not only cannot increase the longitudinal elastic modulus of the matrices, but sometimes decrease their elastic modulus. Of the three selected matrices, steel-silicon matrix would have the most enhancement. Investigation of the effect of nanotube volume fraction on the mechanical properties of nanocomposites shows that increasing the volume fraction of long single-walled carbon nanotube results in increasing the elastic modulus of the nanocomposites.

“…In a similar way, elastic properties for silica nanoparticle/polyimide composites with various nanoparticle/polymer interfacial treatments were investigated through an effective interface model [12]. Additionally, the authors utilized the ECM method to study the effect of SWCNT orientation on the shear modulus of polymeric matrices reinforced with this type of carbon nanofillers [13]. In the proposed method, first, a combined MD/continuum elasticity theory was introduced to obtain the geometrical and mechanical characteristics of the equivalent fiber representing the CNT and its neighboring polymer.…”

With ever increasing the applications of metal matrix nanocomposites (MMNCs) reinforced with carbon nanofillers, demand for accurate and effective modeling techniques in this area has been increased in recent years. To provide such a route, this study is dedicated to apply information form interfacial atomic interactions in modified continuum models implemented to analyze the mechanical behavior of these nanocomposites. In the proposed methodology, the metal matrix is considered as a continuous medium. Meanwhile, to capture the atomicscale phenomena governing the problem, the carbon nanofiller, local metal atoms neighboring it, and the nanofiller/metal interface are analyzed using molecular dynamics (MD) simulations. Subsequently, employing the equivalent continuum modeling (ECM) concept, geometrical and mechanical characteristics of the equivalent nanofiller is obtained in each case and introduced in a finite element analysis (FEA). It is demonstrated that the atomistically informed FEA can successfully reproduce the results of full atomistic MD simulations with ignorable run-time compared to that of this method. Finally, constructing several computational cells with different metal matrices and reinforcing agents, the developed MD/FE multiscale approach is utilized to capture the influences of temperature, nanofiller geometry and orientation, its volume fraction and interfacial interactions on the axial elastic constants of these nanocomposites.
