Pseudo-Villari Experimental Characterization of Magneto-Rheological Elastomers
2020Magneto-rheological elastomers (MRE) are composite materials with magnetically polarized particles dispersed in an elastomeric soft matrix. These materials are an important branch of the smart material family being the mechanical and rheological properties can be reversibly changed upon exposure to a magnetic field.

Characteristics of Magneto-Rheological Elastomer under Stick-Slip Condition
Key Engineering Materials, 2020This paper examines the characteristics of stick-slip phenomena between the glass plate and Magneto-Rheological Elastomer (MRE) surface. Stick-slip phenomena are the spontaneous jerking motion that occurs while two objects are sliding over each other, usually accompanied by noise.

Dynamic Characterization of Magneto-Rheological Elastomers in Shear Mode
IEEE Transactions on Magnetics, 2009The paper presents dynamic shear properties of magneto-rheological elastomers (MREs) under various loading conditions. It particularly focuses on characterization of MREs under compression-shear type combined loading, as it represents realistic loading conditions in various engineering systems and structures.

Magnetomechanical Behavior on Fe/Polyurethane Magneto Rheological Elastomers
2009 Fifth International Conference on MEMS NANO, and Smart Systems, 2009The elastic modulus and shear stress of the Fe-PU Magneto Rheological Elastomers (MRE) have been mechanically characterized by a custom made experimental set up attached with the conventional Universal Testing Machine (UTM). This set up has the ability to generate magnetic field on its own so as to influence the size of the particle and volume fraction

Micropatterned Magneto-Rheological Elastomers to Drive Changes in Cardiomyocyte Alignment
Journal of Visualized ExperimentsSubstrate-associated cues, such as mechanical and topographic, profoundly influence cellular response. However, much of the foundational research employs static or isolated effects. The direction and timescale of these mechanical effects on emergent cellular responses remain largely unexplored.

Nonlinear dynamic characteristics of magneto-rheological visco-elastomers
Science China Technological Sciences, 2013The smart magneto-rheological visco-elastomer (MRVE) has a promising application to vibration control. Its dynamic characteristics are described by complex moduli which are applicable to linear dynamics. However, experimental results show remarkable nonlinear relations between force and deformation for certain large deformations, and the nonlinear ...

The Evaluation of Absorption Performance of Magneto-Rheological (MR) Elastomer
Advanced Materials Research, 2015This study examines the relation between the thickness of a specimen and the weight of an impactor for evaluating the shock absorption performance of magneto-rheological (MR) elastomers with and without a magnetic field. The shock absorption performance can be evaluated by calculating impact energy.

Two-dimensional magnetic property measurement for magneto-rheological elastomer
Journal of Applied Physics, 2013Magneto-rheological elastomer (MRE) is a new kind of smart material. Its rheological properties can be altered and controlled in a real time manner when it is applied an external magnetic field. For calculating magnetic properties of MRE material, usually Maxwell-Garnet equation is used to acquire an approximately effective permeability.

Micromechanical analysis on tensile modulus of structured magneto-rheological elastomer
Smart Materials and Structures, 2016This paper proposed a micromechanical model to investigate the tensile modulus of structured magnetorheological elastomers (MRE) to understand its anisotropic properties. A three parameter representative volume element (RVE) model was presented to describe the microscopic structure, where particles could be organized in layer-like or chain-like ...

Magneto-rheological response of elastomer composites with hybrid-magnetic fillers
Smart Materials and Structures, 2014We study the magneto-rheological response of hybrid-magnetic elastomer composites consisting of two different magnetic filler particles at fixed overall concentration. Thereby, we focus on an optimization of mechanical and magnetic properties by combining highly reinforcing magnetic nano-particles (MagSilica) with micro-sized carbonyl-iron particles ...
