Behavior of magnetorheological elastomers with coated particles
Iron particle coating can improve the behavior of magnetorheological elastomers (MREs) by inhibiting iron particle rusting; however, such a process can change physical properties of MREs such as oxidation resistance, shear modulus, and stiffness change due to an applied magnetic field. In this study, MRE samples are fabricated with regular and polymerized iron particles. To investigate the poss...
متن کاملMagnetorheological elastomers – possibilities and limitations
The mechanical properties of magnetorheological (MR) materials can be changed continuously, rapidly and reversibly by an applied magnetic field. Solid MR materials consist of magnetically polarisable particles, generally iron, in an elastomer matrix. The required iron concentration is high, about 30% by volume. Problems and solutions will be discussed related to MR-technology. Finally long-term...
متن کاملThermoresistance and Giant Magnetoresistance of Magnetorheological Elastomers
A new magnetorheological elastomer composite (MRE) was developed with a resistance which is strongly sensitive both to temperature and pressure. The electrical resistance of this MRE was investigated versus pressure and temperature. The resistance of the composite was recorded versus pressure for seven different values of the temperature. The mechanism of electrical conduction was modeled and a...
متن کاملComputational Modeling of Ferromagnetics and Magnetorheological Elastomers
The aim of this work is to present new variational-based computational modeling approaches for selected materials that have coupled magnetic and mechanical properties. In order to solve the magnetomechanically coupled boundary value problems, we employ the finite element method and also discuss certain aspects that are peculiar to magnetomechanical problems such as the unity constraint on the m...
متن کاملExperimental and theoretical investigation of magnetorheological elastomers with layered mesostructures
Magnetorheological elastomer (MRE) is a type of smart material which can vary its shear modulus rapidly, continuously and reversibly, by the external magnetic fi eld. MRE has attracted increasing attention and been widely used in various applications. Generally it has been created by dispersing magnetic fi ller particles in polymer matrices. Most current studies are focusing on the microstructu...
