“…The authors showed that increasing the frequency ratio yields an increase in the values of the maximum deflection as well as decreasing in the magnitudes of the frequency ratio leads to a decrease in the amounts of the maximum deflection which was correct for higher values of load velocity than a specified magnitude. Roudbari et al [427] studied transient responses of similar interacting SWBNNTs acted upon by the movement of a nanoparticle. Electromechanical coupling behavior and nonlocal elasticity effect proposed by using respectively piezoelectricity as well as nonlocal theories.…”

Nowadays, the mechanical characteristics of micro-/nano-structures in the various types of engineering disciplines are considered as remarkable criteria which may restrict the performance of small-scale structures in the reality for a certain application. This paper deals with a comprehensive review pertinent to using the nonlocal strain-gradient continuum mechanics model of size-dependent micro-/nano-beams/-plates. According to the non-classical features of materials, using size-dependent continuum mechanics theories is mandatory to investigate accurately the mechanical characteristics of the micro-/nano-structures. Recently, the number of researches related to the analysis of micro-/nano-structures with various geometry including beams as well as plates is considerable. In this regard, the mechanical behavior of these structures induced by different loadings such as vibration, wave propagation, and buckling behavior associated with the nonlocal strain-gradient continuum mechanics model is presented in this review work. Proposing the most valuable literature pertinent to the nonlocal strain-gradient continuum mechanics theory of micro-/nano-beams/plates is the main objective of this detailed survey.

“…Understanding the dynamic motion of nanoparticles is critical for MEMS/NEMS and microfluidics [32]. For example, in biological and colloidal science applications, nanotubes and nanobeams are exploited to transport drug materials into targeted nano-sized molecules to change the behavior of cancer cells [33]. Therefore, understanding the process of mass transport and the dynamic response of micro/nanobeams under such loadings would be of great importance for optimal designs [34].…”

This paper presents for the first time a closed-form solution of the dynamic response of sigmoid bidirectional functionally graded (SBDFG) microbeams under moving harmonic load and thermal environmental conditions. The formulation is established in the context of the modified couple stress theory to integrate the effects of microstructure. On the basis of the elasticity theory, nonclassical governing equations are derived by using Hamilton’s principle in combination with the parabolic higher-order shear deformation theory considering the physical neutral plane concept. Sigmoid distribution functions are used to describe the temperature-dependent thermomechanical material of bulk continuums of the beam in both the axial and thickness directions, and the gradation of the material length scale parameter is also considered. Linear and nonlinear temperature profiles are considered to present the environmental thermal loads. The Laplace transform is exploited for the first time to evaluate the closed-form solution of the proposed model for a simply supported (SS) boundary condition. The solution is verified by comparing the predicted fundamental frequency and dynamic response with the previously published results. A parametric study is conducted to explore the impacts of gradient indices in both directions, graded material length scale parameters, thermal loads, and moving speed of the acted load on the dynamic response of microbeams. The results can serve as a principle for evaluating the multi-functional and optimal design of microbeams acted upon by a moving load.
