Abstract: Magnetorheological elastomer (MRE), which belongs to the family of filled elastomer, tends to exhibit strain dependent characteristics under dynamic loading. The strain dependency in MRE is different compared to the conventional filled elastomers, as the magnetic field induced interactions between the fillers impart additional complexities. In the present study, the strain dependent characteristic of isotropic MRE is evaluated from the variation in the dynamic blocked transfer stiffness measured from the force displacement system Lissajous plots. Experiments are performed at different strain levels by varying the magnetic field and the excitation frequency. Results of experiments revealed the disparity in strain dependent characteristics of MRE under magnetized and non-magnetized state. The strain dependency is more pronounced under non-magnetized state of MRE. Within the tested strain level, the field induced property enhancement in MRE is increased with an increase in strain. This difference in strain dependent characteristic of MRE is interpreted by adapting bound rubber model. 2016, Springer-Verlag Berlin Heidelberg.
