Gubanov model for vacuum packed particles

Abstract

The present work mainly focuses on modeling of the mechanical properties of the vacuum packed particles. Such structures are composed on the basis of loose granular materials encapsulated in a hermetic space. Initially granular system behaves like a classical plastic mass. When the internal pressure is pumped out of the system, what was baggy bulk transforms into solid (semisolid) state. Rheological Gubanov model is adopted to describe uniaxial compression loading experimental results of specially performed testing specimens. In the final part of the paper some numerical results are presented. © Springer International Publishing Switzerland 2014.
