The goal of the project was to design and fabricate a Split-Hopkinson Pressure Bar (SHPB) testing setup to study mechanical response of materials under dynamic loading. The setup consists of three major components: gas gun, incident bar, and transmission bar, with a specimen placed between the bars. The projectile hits the incident bar causing a high amplitude stress pulse which propagates through bars which can be analyzed to determine the specimen stress and strain. A gas gun was designed to launch projectiles up to 18” of length at velocities up to 100 m/s. The SHPB setup is mounted onto a rigid platform in order to provide structural support for different bars. The test setup described in this report features 6’ long incident and 3’ long transmission bars made up of steel and aluminum.
