TLDR
In this paper, a rheological model was developed to simulate the dynamic behavior of magnetorheological elastomers (MREs) and the hysteresis loop from shear strain-shear stress plots, which determines the shear modulus and loss factor, were obtained from substituting cyclic loading into these constitutive relationships.Abstract:
A rheological model is described that was developed to simulate the dynamic behavior of magnetorheological elastomers (MREs). The viscoelasticity of the polymer composite, magnetic field-induced properties and interfacial slippage between the matrix and particles were modeled by analogy with a standard linear solid model, a stiffness variable spring, and a spring-Coulomb friction slider, respectively. The loading history and rate dependent constitutive relationships for MREs were derived from the rheological model. The hysteresis loop from shear strain-shear stress plots, which determines the shear modulus and loss factor, were obtained from substituting cyclic loading into these constitutive relationships. The dynamic behavior of MREs was simulated by changing parameters in the rheological model to influence MREs’ performance. The simulation results verified the effectiveness of the model.read more

The Dynamic Properties of Carbon Black-Loaded Natural Rubber Vulcanizates. Part I
TL;DR: In this article, the dynamic shear modulus at very high strains, (G∞), of carbon black filler loaded vulcanizates is regarded as due to the product of hydrodynamic interaction due to filler particles, and a second factor for which evidence is given suggesting that it arises from a few strong linkages which are known to link filler particles to the matrix.

A model of the behaviour of magnetorheological materials
TL;DR: In this paper, a quasi-static, one-dimensional model is developed that examines the mechanical and magnetic properties of magnetorheological materials, and the model attempts to account for magnetic nonlinearities and saturation by establishing a mechanism by which magnetic flux density is distributed within the composite material.

Model of magnetorheological elastomers
TL;DR: In this paper, the authors used finite element analysis to show that the shear modulus of typical elastomers is about 50% of the zero-field modulus at saturation and the optimum particle volume fraction for the largest fractional change in modulus is predicted to be 27%.
