UREAD Impact Behaviour Using Silicon Based Materials

چکیده
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.

Most engineering products are designed to either deliver or withstand a specific maximum force or level of energy. It is important however that the design of a structure or a machine incorporates an external or internal mechanism to overcome excessive loading, so as to reduce human discomfort and unsafe operations. Most high-energy absorption devices are not re-usable and have rebound forces co...
متن کاملThe plastic behaviour of silicon subjected to micro-indentation
Micro-indentation is widely used in evaluating the mechanical properties of ceramics. It is also an important measure in the study of machinability of brittle materials. Because of the complexity of interaction in the vicinity of the contact zone between the indenter and work material, an analytical or experimental method is unable to predict the detailed evolution process of deformation. With ...

The utilisation of crystalline semiconductor materials as detectors and devices operating in high radiation environments, at the future particle colliders, in space applications, in medicine and industry, makes necessary to obtain radiation harder materials. Diamond, SiC and different A III B V compounds (GaAs, GaP, InP, InAs, InSb) are possible competitors for silicon to different electronic d...

متن کاملResonance experiments on microstructures
Using piezoelectric excitation, the resonance frequencies of microstructures made of monocrystalline silicon or metal alloys are experimentally determined. Several resonance frequencies are found for each microstructure. A scanning vibrometer allows to determine the corresponding modal shape for frequencies lying between 40 Hz and 160 kHz. In combination with a numerical analysis, this data all...
