We report on our efforts to model nonlinear dynamics in elastomers. Our efforts include the development of computational techniques for simulation studies and for use in inverse or system identification problems. As a first step towards the full dynamic case, we present the static inverse problem, with experimental results. We also present results from the simulation of dynamic experiments. 1 Introduction A problem of fundamental interest and great importance in modern material sciences is the development of new materials for use as both passive and active vibration suppression devices. Materials such as elastomers, rubber-like composites typically filled with inactive particles such as carbon black and silica, are frequently used in parts such as engine mounts and springs. One could imagine using active fillers, such as piezoelectric, magnetic, or conductive particles, to create a "smart" material which could be used as an active vibration suppression device. In the quest to develop...
