On the Dynamics and Control of Mechanical Energy Propagation in Granular Systems

Abstract

It would be interesting to envision a light, thin and heat resistant multifunctional material which when exposed to some kind of a blast wave at one side manages to rapidly absorb and redistribute the received energy into localized tiny hot spot regions between the layers thereby protecting a significant part of the blast from getting transmitted to the other end. Development of the scientific understanding needed for insuring that the perturbation does not become thermalized has been the focus of the proposed study. We believe that such research may find potential application in the development of novel impact absorption materials. The research shows that it is indeed possible to develop nonlinear oscillator systems that are capable of harnessing perturbations via multiple intrinsic localized modes. The studies also suggest that such energy redistribution may be possible to accomplish for a broad range of frequencies than what may have been thought to be possible in earlier pilot work
