This work deals with a comprehensive theoretical and numerical framework that allows the modeling of finite strain magnetorheological elastomers (MREs) comprising mechanically soft nonlinear elastic–viscoelastic polymer phases magnetically hard (i.e. dissipative) or purely energetic) magnetic phases. The is presented in general manner implemented using element method. Two software implementations are developed, one FEniCS other Abaqus. A detailed analysis schemes used to model surrounding air made their pros cons discussed. proposed simulate two geometries directly relevant recent applications MREs. first two-dimensional example simulates beam consisting single wavy-chain particles. subjected transverse actuation loads induce important vertical deflections. Despite overall small local strains beam, significant viscoelastic effect observed when high-rate fields applied. torque for particles also analyze geometry found be relatively good agreement rest approaches fields. second discusses rotation three-dimensional ellipsoid embedded cubic elastomer domain, while ensemble lies inside larger domain. Non-monotonic uniaxial rotating applied leading complex, non-monotonic rotations ellipsoidal particle. cases exhibit differences, whereas viscoelasticity strong coupling magnetization but not dissipative amplitude. Extensive supplementary material provides all details our as well animated visualization results.

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

Abstract Hard-magnetic soft materials (hMSMs) are smart composites that consist of a mechanically polymer matrix impregnated with hard magnetic filler particles. This dual-phase composition renders them exceptional magneto-mechanical properties allow to undergo large reversible deformations under the influence external fields. Over last decade, hMSMs have found extensive applications in robotics, adaptive structures, and biomedical devices. However, despite their widespread utility, they pose considerable challenges fabrication characterization owing multi-phase nature, miniature length scales, nonlinear material behavior. Although noteworthy attempts been made understand coupled rudimentary concepts inter-phase interactions give rise mechanical nonlinearity remain insufficiently understood, this impedes further advancements. holistic review addresses these standalone bridges gaps by providing thorough examination myriad techniques, applications, experimental, modeling approaches. Specifically, presents wide spectrum ranging from traditional molding cutting-edge four-dimensional printing, unbounded prospects diverse fields research. The covers various approaches, including continuum frameworks encompassing phenomenological homogenization models, as well microstructural models. Additionally, it emerging techniques like machine learning-based context hMSMs. Finally, expansive landscape promising systems is provided for better understanding prospective

Hard-magnetic soft materials (HMSMs), as a sub-class of magneto-active polymers, consist polymeric matrix filled with particles high remnant magnetic induction. The application external flux on HMSMs induces moment its material particles. From the angular momentum balance law, it is deduced that Cauchy stress tensor in these cannot be symmetric. Therefore, micropolar continuum theory, inherent asymmetric tensor, rational candidate for modeling deformation materials. In present contribution, an HMSM modeled three-dimensional body, which subjected to stimuli. resulting from interaction internal and fluxes plays role body couple formulation. After developing main formulation, due highly nonlinear nature governing equations, weak form equations linearization perform numerical simulations presented. To demonstrate capability performance developed formulations, several examples are provided. It shown formulation can successfully predict under various loading boundary conditions.
