Round-Robin test of split Hopkinson pressure bar

International Journal of Impact Engineering, 2019
Abstract A Round-Robin test using split Hopkinson pressure bars (SHPBs) has been conducted by four universities: Swinburne University of Technology (SUT), Australia; University of Sao Paulo (USP), Brazil; University of Cape Town (UCT), South Africa; and Nanyang Technological University (NTU), Singapore. Each university had different sets of SHPBs and

A versatile split Hopkinson pressure bar using electromagnetic loading

International Journal of Impact Engineering, 2018
Abstract This paper presents a novel electromagnetic split Hopkinson pressure bar (ESHPB), which employs the electromagnetic energy conversion technique of LC circuit to generate directly the incident stress pulse. Such a versatile technique can generate easily compressive as well as tensile incident pulses.

Split Hopkinson Pressure Bar Graphical Analysis Tool

Experimental Mechanics, 2016
An open-source Split Hopkinson Pressure Bar graphical data analysis tool has been developed. Written in Matlab®, the code can be freely distributed either as an executable binary or editable Matlab files. Beginning with raw voltages from two strain gages along with the incident/transmitted bars’ mechanical and geometrical properties, the user can ...
