This work deals with new "smart systems" that are based on granular materials. These systems consist of a tight flexible sleeve, which is filled with a granular material. The air is then pumped out of the sleeve, causing underpressure, compressing the granules and so making the system more rigid and changing its damping characteristics. This allows for quick, easy, and inexpensive controls of the damping and stiffness of such systems. The aim of this paper is to present the experimental results of uniaxial tests of a sleeve filled with granular materials. These results support the modeling of such a system filled with a granular material using the Bodner-Partom viscoplastic constitutive law.
