Modeling the behavior of magnetorheological elastomers under different loading conditions (original) (raw)

Active and Passive Smart Structures and Integrated Systems IX, 2020

Abstract

This paper presents a rheological model that was developed to stimulate the experimental behavior of magnetorheological elastomers (MREs) under varying loading conditions (magnetic field, strain amplitude and frequency). Magnetorheological elastomers (MREs) were fabricated and tested using double lap shear experiment setup under different strain amplitudes, magnetic fields and frequencies. A linear visco-elastic rheological model consists of seven parameters to represent both viscous and elastic behavior of MREs. The parameters under varying loading conditions were identified and optimized using the data recorded from experiments. The experimental results were then compared with model predicted values which demonstrate that the seven-parameter model predicts MRE behavior well.
