“…Multiscale methods are generally classified into hierarchical, semi-concurrent, and concurrent methods. [152][153][154][155] In hierarchical or non-concurrent multiscale approaches, information of the fine-scale is passed to the coarse-scale. A macroscopic constitutive model is assumed and parameters of the model are computed from the microstructure.…”

Nanotechnology has opened a new area in science and engineering, leading to the development of novel nano-electromechanical systems such as nanoresonators with ultra-high resonant frequencies. The ultra-high-frequency resonators facilitate wide-ranging applications such as ultra-high sensitive sensing, molecular transportation, molecular separation, high-frequency signal processing, and biological imaging. This paper reviews recent studies on dynamic characteristics of nanoresonators. A variety of theoretical approaches, i.e., continuum modeling, molecular simulations, and multiscale methods, in modeling of nanoresonators are reviewed. The potential application of nanoresonators in design of sensor devices and molecular transportation systems is introduced. The essence of nanoresonator sensors for detection of atoms and molecules with vibration and wave propagation analyses is outlined. The sensitivity of the resonator sensors and their feasibility in detecting different atoms and molecules are particularly discussed. Furthermore, the applicability of molecular transportation using the propagation of mechanical waves in nanoresonators is presented. An extended application of the transportation methods for building nanofiltering systems with ultra-high selectivity is surveyed. The article aims to provide an up-to-date review on the mechanical properties and applications of nanoresonators, and inspire additional potential of the resonators.

“…The coupling of molecular space to continuum domain is accomplished through bridging domain methods which can be recognized as the main challenge of these methods. Transferring structure‐property relations from molecular level to continuum level is considered as the most challenging issue in multi‐scale modeling of nanocomposites where it is necessary to conciliate encountered length and time scales over several orders of magnitudes . Recently, a multi‐scale model bridging length and time scales from molecular to continuum levels wherein nanoscale simulations obtained from MDs were homogenized to a continuum constitutive model for resin .…”

A literature review is conducted on performed investigations for characterizing Young's modulus of nanoclay platelet as the reinforcing agent of nanoclay/polymer nanocomposites from both experimental and theoretical aspects. The observed discrepancies in the reported results are discussed accordingly. All available investigations for predicting mechanical properties of nanoclay reinforced polymers are also reviewed. The employed methods in ongoing studies are categorized into three groups as atomistic, continuum and multiscale modeling techniques. Those challenging issues which are still in need of more accurate understanding and discussion are identified and outlined through a gap analysis on current investigations. The introduced shortcomings can be considered as prospective research areas for the future studies in the field of estimating mechanical properties of nanoclay based composites. POLYM.
