In this paper, we present a novel approach to modeling and analysis of Vacuum Packed Particle dampers (VPP dampers) with the use of Discrete Element Method (DEM). VPP dampers are composed of loose granular medium encapsulated in a hermetic envelope, with controlled pressure inside the envelope. By changing the level of underpressure inside the envelope, one can control mechanical properties of the system. The main novelty of the DEM model proposed in this paper is the method to treat special (pressure) boundary conditions at the envelope. The model has been implemented within the open-source Yade DEM software. Preliminary results are presented and discussed in the paper. The qualitative agreement with experimental results has been achieved.

Element Method

The mechanics models formed by packed circular discrete elements and randomly distributed in a specified region were used to investigate the mechanics properties of granite, and some different sizes of discrete element models were carried out to study the size effect of mechanics properties. The simulation results suggest that there is no obvious size effect for Poisson’s ratio, compressive strength and Young’s modulus. However, the value of bending strength decreases with the increasing of the model size.
