Abstract
The study deals with experimental testing and estimating the modified Dahl model parameters of magnetorheological elastomers (MREs) differing in volumetric concentrations of carbonyl iron particles (CIP). The authors present briefly an overview of scientific reports relating to MREs research. Next, they describe the structure and magnetic properties of two fabricated MREs, which were investigated using a scanning electron microscope, a magnetometer and a gaussmeter. Then, they reveal the structure of a specially engineered test rig for materials sample examination and present a scenario of experiments. Next, the test results of the material’s mechanical properties conducted in the absence and presence of a magnetic field were discussed. Then, they describe a modified Dahl model of the material followed by parameters estimation and validation procedure. Finally, the authors summarise the test results and outline further research steps.
