“…Car bumpers are also examples of energy dissipation devices based upon plastic deformation, not deemed re-usable. A design and FEA crash simulation for a composite car bumper is reported in [10], an optimized bumper systems for pedestrian lower-leg protection in [11], and an experimental study on characteristics of shock absorbers of impact energy of passenger coaches in [12]. This is also the case for a new generation of guardrails [9]; like with the others the nature of the working mechanism will not allow re-usage.…”

Several methodologies and techniques are currently available so as to dissipate energy in engineering systems; most of them are either not re-usable, or complex in mechanism. This paper introduces an innovative re-usable energy absorption device, based upon the working principles of Equal Channel Angular Extrusion, and known as UREAD (Universal Re-usable Energy Absorption Device). This study compares the behaviour of different "low-density" deformable materials (a range of silicon rubber grades) inserted in a UREAD unit and loaded under impact condition. The energy absorbed was experimentally measured and compared against the impact energy. It was possible to dissipate levels as high as 74.91% of the impact energy when using a simple set-up, and the device re-usability was demonstrated.
