Experiment med en Split Hopkinsonstång
Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
This report describes how a torsional wave is generated and propagated in aluminum bars, as well as how this is used to apply shear stress to a specimen.The laboratory equipment that was used during the experiment is mostly known as a Split Hopkinson Bar. It consists of an incident and transmitting bar with a specimen attached between the bars. By using a clamp, the incident bar could be fixed which made it possible to store a torque in the section of the bar between the clamp and the loading end. When the clamp was removed, the stored torque was released and a torsional wave propagated towards the specimen. With the aid of strain gages the wave were measured and from them the torque and the twist angle of the specimen were calculated.The main features of this report describes how a measurement of a torsional wave in a Split Hopkinson Bar is done, but also, why a tubular specimen is favourable to use instead of a solid specimen.This report can also be used as a guide when conducting similar experiments with a Torsional Split Hopkinson Bar.
