Influence of Polyurethane Properties on Mechanical Performances of Magnetorheological Elastomers
Magnetorheological elastomers (MREs) are mainly composed of magnetizable particles and elastic polymer. The polymer matrix plays an important role in mechanical performances of MREs. In this study, the polyurethane (PU), which is synthesized by using toluene diisocyanate (TDI) and poly (propylene glycol) (PPG-220), is selected as a matrix because it has better degradation stability than natural...
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 کاملConstitutive modeling of the Mullins effect and cyclic stress softening in filled elastomers.
The large strain behavior of filled rubbers is characterized by the strong Mullins effect, permanent set, and induced anisotropy. Strain controlled cyclic tests also exhibit a pronounced hysteresis as a strain rate independent phenomenon. Prediction of these inelastic features in elastomers is an important challenge with immense industrial and technological relevance. In the present paper, a mi...
