“…The most common applications of the MREs include vibration absorbers, vibration isolators, dampers, and shock absorbers for vehicles [15,16,[78][79][80][81][82][83][84][85][86]. Another type of application of MREs composites is sandwich structures, where an MRE acts as a smart core in the structures such as sandwich beams [87][88][89][90][91][92]. More recently, MREs receive significant attention in other applications such as sensors, for example, MRE-based microelectromechanical systems (MEMS) magnetometer, magneto-resistor, flexible tactile sensor/display [93][94][95][96], flexible microfluid transport system [97], and peristaltic pump [98] and even as a shape memory polymer [99].…”

“…where r and ε represent the distance between dipoles in horizontal and vertical directions, respectively. Quantity J ¼ φVJ p signifies the magnitude of dipole moment, J p ¼ μ 0 M p is the magnitude of dipole moment per particle volume, and M p is the magnetic field strength induced in the particle which can be calculated using Frohlich-Kennelly law described in Equation (38). Hence, the horizontal and vertical forces between particles can be written as follows…”

“…It has been unanimously reported that the shear moduli of MREs increase with increasing magnetic field strength. Owing to their field-dependent modulus, contactless control, and the shape-morphing features, MREs have attracted much attention over the past few years, making them an ideal smart material candidates to address stiffness or modulus tunability requirements in different engineering applications such as smart sensors and actuators, adaptive vibration isolators, [25][26][27][28] tunable vibration absorbers (TVAs), [29][30][31][32][33] adaptive dampers, [34][35][36] sandwich beams, [37][38][39][40] and biomedical engineering such as tissue engineering [41][42][43][44] and drug delivery. [45,46] There have also been several review papers in the literature that discuss the potential applications of such materials.…”

The magnetorheological elastomers (MREs) are novel multifunctional materials wherein their viscoelastic properties can be varied instantly under an application of applied magnetic field. Due to their field‐dependent stiffness and damping properties, MREs are widely used in the development and design of MRE‐based adaptive vibration isolators and absorbers and also biomedical engineering. Moreover, MREs due to their inherent magnetostriction effect have enormous potential for the development of soft actuators. The dynamic behavior of MREs is affected by various material parameters (e.g., matrix and particle types, particle concentration, additives) as well as mechanical and magnetic loading parameters (e.g., frequency, amplitude, temperature, magnetic flux density). Understanding and predicting the effect of materials and loading parameters on the response behavior of MREs are of paramount importance for the design of MRE‐based adaptive structures and systems. This review paper mainly aims to provide a comprehensive study of material constitutive models to predict the nonlinear magnetomechanical behavior of MREs. Particular emphasis is paid to physics‐based models including continuum‐ and microstructure‐based models. Moreover, phenomenological models describing the dynamic magnetoviscoelastic behavior of MREs as well as the effect of temperature on the magnetomechanical behavior of such materials are properly addressed.

“…Among coupled thermo-mechanical problems, Eltaher et al [7] investigated the influence of a thermal loading and shear force on the nonlocal buckling response of nanobeams via higher-order shear deformation Eringen beam theories. Similarly, Ebrahimi and Farazmandnia [8] investigated the thermo-mechanical vibration of sandwich FG-CNTRC beams within a Timoshenko-based beam approach; Sobhy and Zenkour [9] illustrated the influence of a magnetic field on the thermo-mechanical buckling and vibration response of FG-CNTRC nanobeams with a viscoelastic substrate. In line with the previous works, Daikh and Megueni [10] studied the thermal buckling of FG sandwich higher-order plates with material temperature-dependent properties under a nonlinear temperature rise; Arefi and Arani [11] combined a third-order shear deformation approach together with the nonlocal elasticity to study the static deflection of FG nanobeams under a coupled thermoelectro-magneto-mechanical environment.…”

Buckling Analysis of CNTRC Curved Sandwich Nanobeams in Thermal Environment

et al. 2021

View full text Add to dashboard Cite

This paper presents a mathematical continuum model to investigate the static stability buckling of cross-ply single-walled (SW) carbon nanotube reinforced composite (CNTRC) curved sandwich nanobeams in thermal environment, based on a novel quasi-3D higher-order shear deformation theory. The study considers possible nano-scale size effects in agreement with a nonlocal strain gradient theory, including a higher-order nonlocal parameter (material scale) and gradient length scale (size scale), to account for size-dependent properties. Several types of reinforcement material distributions are assumed, namely a uniform distribution (UD) as well as X- and O- functionally graded (FG) distributions. The material properties are also assumed to be temperature-dependent in agreement with the Touloukian principle. The problem is solved in closed form by applying the Galerkin method, where a numerical study is performed systematically to validate the proposed model, and check for the effects of several factors on the buckling response of CNTRC curved sandwich nanobeams, including the reinforcement material distributions, boundary conditions, length scale and nonlocal parameters, together with some geometry properties, such as the opening angle and slenderness ratio. The proposed model is verified to be an effective theoretical tool to treat the thermal buckling response of curved CNTRC sandwich nanobeams, ranging from macroscale to nanoscale, whose examples could be of great interest for the design of many nanostructural components in different engineering applications.
