摘要

The tensile split Hopkinson pressure bar (SHPB), one of the SHPB types, is a valued equipment for researchers and material scientists for material characterization at high strain rate (HSR). However, comprehensive information on the design and development of the tensile SHPB apparatus is still limited. This article aims to explain the process of designing, developing, and commissioning a tensile SHPB setup in an extensive manner. The structural design, material selection for bars, and considerations for the length and diameter of bars have been covered. Specimen design for composites, along with materials such as metals and acrylics, have been addressed. The study also covers the principles of data collection and instrumentation, including oscilloscopes, chronographs, Wheatstone bridges, strain conditioning amplifiers, and strain gauges. The propelling mechanism and how it works are explained in detail, and then the tensile SHPB calibrating processes are also described.
