The conceptual design of smart crash energy absorber made of vacuum packed particles (VPP) is presented in this work. Absorber is able to change the flexural stiffness and as a result the amount of dissipated energy depending on the impact conditions. An important feature of the absorber is the possibility of multiple use what is caused by the special properties of granular structure. Vaccum packed particles is the structure composed of granular material inside plastomer enveloped. When the pressure inside is equal or higher than atmospheric pressure system behaves similarly to a liquid, otherwise it has properties similar to viscoplastic solid. The physical properties of the structure may be rapidly change by pulling out the pressure from the system. Due to this properties the vaccum packed particles can be treat as a smart material.
