Laboratory testing and modelling of magnetorheological elastomers in tension mode

The study deals with experimental testing and estimating the modified Dahl model parameters of magnetorheological elasto-mers (MREs) differing in volumetric concentrations of carbonyl iron particles (CIP). The authors present briefly an overview of scientific re-ports relating to MREs research. Next, they describe the structure and magnetic properties of two fabricated MREs, which were investigat-ed 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 proper-ties 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.
