Dem modeling of vacuum packed particles dampers

We present a method based on Discrete Element Method (DEM) to modeling the Vacuum Packed Particles (VPP)—a class of smart materials/smart structures. Mechanical properties of VPP can be simply adjusted by controlling the underpressure, which makes the structures very interesting from practical point of view, giving raise to numerous applications, including smart grippers [2], dampers [1, 6] or medical tools [5].
