This report is about using a high speed camera to capture the Split Hopkinson Bar test, as the action is too fast to be observed by the naked human eye. The high speed video is then analysed to determine the deformation of the specimen with time, using the software ‘Photron Motion Tools’ that is for use with the high speed camera in the laboratory, the Photron FASTCAM 1024 PCI. The striker tube and anvil bar of the apparatus are also analysed. This Final Year Project is a collaboration with two other students doing the Split Hopkinson Bar test, and focuses on the photography aspect, with some analysis of the deformation of the specimen.In total, 9 sets of parameters, known as conditions in this report, are being analysed in depth, including how different sections of the specimens deform with respect to each other and with respect to the whole length of the specimen. A stress-strain graph is also plotted after getting the experimental values of stress from the two students the author is collaborating with.
