Senior students are always challenged to apply their engineering knowledge and research skills gained from an engineering curriculum toward design and implementation of challenging senior design projects. Split Hopkinson Pressure Bar (SHPB) is an apparatus that is used to study materials behavior under high speed deformation, where strain rate is very high. Hopkinson bars are usually custom made based on the needs of customers, who are mostly researchers in universities or research labs. In this work, in a form of a senior design project, the authors provided learning opportunities for engineering students to design a data acquisition system for a small size split Hopkinson pressure bar previously designed by former students. The objectives of this project are to engage a team of students 1) to design a data acquisition system using National Instrument hardware and Labview to collect strain data during high speed deformation testing 2) to design a data processing program to process the strain data collected to stress-strain graph 3) to conduct a number of high speed deformation material testing to validate the performance of the data acquisition system designed.
