Temperature Dependent Dynamic Mechanical Properties of Magnetorheological Elastomers: Experiment and Modeling
Magnetorheological elastomers (MREs) are a group of new smart composite materials which are typically comprised of magnetic particles, non-magnetic matrix, and some additives. Their controllable mechanical properties are dependent on many factors, among which temperature is very important yet lack of understanding due to limited studies. In this paper, a series of experimental studies have been...
متن کاملInfluence 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 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...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولMagnetorheological 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...
