“…Similarly, NR-based MREs are fabricated by mixing NR with filler particles homogeneously by two-roll mill or any other means and pouring into molds. Curing of NR-based MREs is performed in an oven, maintained at 180 °C under specific pressure (200 bar) for a specific time (10 min) to get the final isotropic MRE [ 27 ]. Furthermore, the fabrication of isotropic MRE from scrap tire rubber involves the separation of rubber from metals and fabrics, shredding into powder of 60-mesh size, and analyzing its chemical composition (usually 7% acetone extract, 5.45 ash, 32.9% carbon black, 54.6% hydrocarbon rubber).…”

“…The MRE with a higher CIPs concentration exhibited a larger MR effect under higher magnetic field strength but not as large as reported in the literature in compression mode [ 115 , 116 , 117 ] due to lower magnetic field strengths. In addition, the MR effect in the compression mode was observed to be greater than in the shear mode [ 27 ].…”

“…Although the response time of MRE is slower than MRF [ 19 ], MRE still effectively overcomes the deficiencies of MRF, particularly the particle sedimentation, leakage, and environmental contamination problems [ 20 ]. Due to their rapidly and reversibly controllable properties, including morphological [ 21 ], tomographical [ 22 ], mechanical [ 23 ], dynamic mechanical [ 24 , 25 , 26 ], magneto-mechanical [ 27 , 28 ], magneto-shear [ 29 ], rheological and melt rheological [ 30 ], complex torsional [ 31 ], physicochemical [ 32 ], thermal [ 33 ], friction and wear [ 34 ], fatigue life [ 35 ], and viscoelastic [ 12 ] properties, as well as a fail-safe feature [ 19 ], MREs have a wide range of applications. These applications include damping and smart sensing in vibration absorbers [ 36 , 37 ] and vibration isolators [ 38 , 39 , 40 , 41 ], other sensing devices [ 42 , 43 ], engine mounts, vehicle seat suspension [ 44 ], adaptive stiffness devices, actuators to control the flow [ 31 ], MR elastic polishing composites [ 45 ], seismic dampers and base isolators [ 46 , 47 , 48 , 49 , 50 ], multilayer MRE-based vibration isolators [ 51 ], MREs embedded beams [ 52 ], variable impedance surfaces, artificial muscles [ 24 ], deformable wings [ 53 ], MRE embedded sandwich plates [ 54 ], adaptive blades [ 55 ], active vibration isolation platforms […”

Magnetorheological elastomers (MREs) are magneto-sensitive smart materials, widely used in various applications, i.e., construction, automotive, electrics, electronics, medical, minimally invasive surgery, and robotics. Such a wide field of applications is due to their superior properties, including morphological, dynamic mechanical, magnetorheological, thermal, friction and wear, and complex torsional properties. The objective of this review is to provide a comprehensive review of the recent progress in isotropic MREs, with the main focus on their properties. We first present the background and introduction of the isotropic MREs. Then, the preparation of filler particles, fabrication methods of isotropic MREs, and key parameters of the fabrication process—including types of polymer matrices and filler particles, filler particles size and volume fraction, additives, curing time/temperature, and magnetic field strength—are discussed in a separate section. Additionally, the properties of various isotropic MREs, under specific magnetic field strength and tensile, compressive, or shear loading conditions, are reviewed in detail. The current review concludes with a summary of the properties of isotropic MREs, highlights unexplored research areas in isotropic MREs, and provides an outlook of the future opportunities of this innovative field.

“…This is the point where storage and loss modulus become dependent on the strain. Identification of this LVE limits was briefly discussed by Olabide et al [95]- [97] and Karrabi et al [98]. Durability investigation at the condition that strain is constantly within LVE limits will be a great challenge.…”

An Overview of Durability Evaluations of Elastomer-Based Magnetorheological Materials

Most parts of the failures in structural elements in use were consequences of mechanical durability. Therefore, durability had been one of the critical factors to be considered in designing durable mechanical elements. In magnetorheological elastomer (MRE) materials, the durability process involves different damage mechanisms that result in the degradation of the materials. Increasingly used of outstanding performance of MRE was susceptible to failure under durability performance for various applications. In response to these problems, with limited sources of published articles on MRE durability, an overview of the durability of elastomer based MRE is presented. The study focuses on collecting and analyzing the works including experimental and modeling approaches that have been conducted on MRE durability up to date. Two bibliographic searched databases, Scopus and Web of Science were consulted to collect the final set of articles with the aims to identify current and future trends of MRE durability. Prominence works conducted on MRE durability were also encapsulated in this paper to provide a visual perspective and subsequently motivate researchers to heighten the need for MRE durability investigation.

“…The latter approach, the shear–compression mix-mode vibration isolation, still requires considerable efforts in designing, characterization, modeling, and controlling of the mix-mode isolator since the MREs behavior is quite different in shear and compression mode. In other words, determining the individual contribution of the shear and compression force, along with providing physical interpretation and modeling the shear–compression mixed mode MRE isolators are quite complex tasks as it has been proved by several studies that the linear region or threshold of nonlinearity of MREs is dissimilar in the shear and compression mode (Agirre-Olabide and Elejabarrieta, 2018; Agirre-Olabide et al, 2014; Dargahi et al, 2019a, 2019b; Norouzi et al, 2017; Vatandoost et al, 2017; Wang and Kari, 2019). Moreover, MREs in compression mode show nonlinear behavior even at relatively lower strain amplitudes compared to shear mode (Norouzi et al, 2016; Vatandoost et al, 2020).…”

In this article, a novel bi-directional shear mode magneto-rheological elastomer–based vibration isolator has been designed, fabricated, and characterized to improve the dynamic response and identification of this class of “intellectual” mechanical devices. A heuristic embodiment has been realized in order to design such an isolator wherein both the vertical and horizontal directions can be operated only in the shear mode not only individually but also simultaneously. Two fixtures have been designed for performing the characterization of the magneto-mechanical behavior of the proposed magneto-rheological elastomer isolator in the vertical and horizontal shear modes under wide ranges of strain amplitude (4%–32%), excitation frequency (1–8 Hz), and magnetic flux density (0–220 mT). Experimental results revealed maximum relative magneto-rheological effects of 35% and 27 % in the vertical and horizontal shear modes, respectively. Furthermore, basic mathematical models of single-degree-of-freedom systems, employing the magneto-rheological elastomer–based isolator in the vertical and horizontal shear modes, have been established. The proposed magneto-rheological elastomer isolator in the vertical mode exhibited natural frequency shift of 6.1% by a small increment in the magnetic flux density which approves the potential of the proposed bi-directional shear mode magneto-rheological elastomer–based vibration isolator for vibration control applications, such as seat suspension systems.
