Abstract

Recently, magnetorheological elastomer-based vibration control devices have attracted increasing attention due to their fielddependence of stiffness characteristics. It is crucial to develop a comprehensive model for precisely predicting mechanical behaviorsof magnetorheological elastomers (MREs). In this work, silicon rubber-based MRE samples were prepared and investigated through dy-namic and quasistatic stretch tests. Experimental results suggest that the samples possess an obvious magnetorheological effect, as well asfrequency- and amplitude-dependent mechanical behavior. In order to depict these properties in a unified scheme, an extended fractional-order derivative model was developed to consider the Payne effect using the framework of the Kraus model. A comparison with experimentaldata indicates that this new model is accurate in predicting the mechanical behavior of MREs
