Torsional Split Hopkinson Bar Optimization

Abstract

The Torsional Split Hopkinson Bar is a piece of equipment used to perform testing of materials in order to measure mechanical properties by generating high strain rate shear stress-strain data. It works by propagating a torsional wave through an incident bar, reaching a specimen, and making the wave load the specimen. Once the specimen is loaded, the wave is partially reflected back and is partially transmitted through the transmitter bar. This simplified version of the process has as its objective to determine the load and deformation history of the specimen to obtain various mechanical properties of the material such as shear stress and strain.
