“…2.3), longitudinal and transverse components of the magnetic permeability values were calculated and are shown in table 2; the permeability is larger for high particle content and for lower magnetic fields, and the longitudinal one is larger than the transverse one due to the lower demagnetizing effect in the sample with the aggregates oriented along the applied field. (2) and (7), and using experimental magnetic permeability values (table 2), the modulus was predicted. In two bottom parts of figure 6 experimental storage modulus is compared to the theoretical one obtained using Eqs.…”

“…Dynamic properties of anisotropic MREs are dependent on matrix, particle content and magnetic field. The predominant behaviour is the viscoelastic one, due to the nature of the main component of these materials: silicone rubber or a natural rubber [6,7]. That behaviour have been modelled for MRE materials combining different elements as dashpots and springs in different configurations [8,9].…”

“…2 The fractional derivative model can be used to decrease the number of material parameters, and these parameters have a physical meaning [11]. Using these advantages the viscoelastic behaviour of isotropic [7,12] and anisotropic [13,14] MREs have recently been modelled using fractional derivative models. Agirre-Olabide et al [12] have used four material parameters to simulate the viscoelastic behaviour of isotropic MREs and Xu et al [7] have combined a fractional Kelvin and Maxwell model in parallel configuration developing a higher order model (seven material parameters).…”

International audienceThe storage modulus variation of anisotropic magnetorheological elastomers (MREs) induced by an external magnetic field was modelled in the frequency domain. This involves synthesising five anisotropic MREs with different particle content and measuring its dynamic and magnetic properties. Dynamic properties were measured using a rheometer equipped with a magnetorheological cell and the magnetic permeability of each sample was measured with a vibrating sample magnetometer. Scanning Electron Microscope images were used to determine particle distribution. A four parameter fractional derivative model was used to describe MRE viscoelasticity in the absence of magnetic field and the fitting error was not larger than 1%. Magneto-induced modulus was also studied and two different models were analysed, the one of Jolly et al. (Smart Mater Struct;5:607 (1999)) and the other one of López-López et al. (J Rheol. 56:1209 (2012)). The first model underestimated the influence of the magnetic field for low particle contents while at high ones it overestimated the magnetic field effect, up to 13%. However, in the second model magnetic permeability values were used, and the error between the model prediction and experimental data did not exceed 7%. Hence, a new linear magneto-viscoelastic model was proposed in frequency domain for anisotropic MREs based on López-López et al. model, which predicts the effect of magnetic field on the dynamic shear modulus in function of particle content and frequency

“…[9,12,14,15] A number of researchers have made attempts to improve the damping and stiffness properties of VE dampers by changing rubber interpenetrating polymer network, [21] polymeric material, [22] and rubber matrix. [23] Although various viscoelastic materials have been considered, it is still a challenge to balance the damping and stiffness contributions of a full-scale VE damper. However, the use of high-damping rubber in VE dampers can provide a new path to resolve this.…”

Summary This study explores the mechanical response of a high‐damping rubber damper (HRD) under different loading conditions. HRD is a typical viscoelastic damper that consists of 2 layers of elastomer compound sandwiched between 3 steel plates. The elastomer compound used in this study is a synthetic isoprene rubber reinforced with carbon black and designed to provide high damping capacity with relatively low stiffness. Four damper specimens with a displacement capacity of 75 mm at 300% shear strain were fabricated. Each damper was subjected to harmonic loading to investigate the effects of strain amplitude, loading frequency, strain history, and cyclic loading on the mechanical properties of HRD. Hysteretic force–displacement loops for each loading condition were plotted, and the variations of maximum damper force, equivalent stiffness, storage shear modulus, dissipated energy, loss factor, and equivalent viscous damping ratio with different test parameters were examined. In addition, an analytical model capable of simulating behavior of HRD at various strain amplitudes and loading frequencies was proposed. The experimental results indicate that the developed HRD can provide a damping ratio ranging from 15% to 43% under different loading conditions and has relatively stable hysteresis loops under cyclic loads. In addition, the energy dissipation capacity of the damper significantly increases when the loading frequency is over 0.5 Hz without an increase in stiffness.

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.
