Terminal Ballistic of Aluminium Plate: An Experiment and Numerical Simulation.

This paper presents the terminal ballistic of 3 mm thickness aluminium plate impacted by fragment simulating projectile (FSP). Up to days, not many researchers are keen into terminal ballistic. They are more focus towards ballistic limit. Therefore, there is a need to highlight terminal ballistic as such in this study. The experiment was conducted at the Science and Technology Research Institute for Defence (STRIDE) Batu Arang, Selangor. For recording purpose, digital high speed camera with the capability of 250,000 frames per second (max) and the highest resolution 1024x1024 was used. For the data acquisition and processing, Photron Fastcam Viewer (PFV) software was used. For numerical simulation purpose, commercial software code Hyperworks was employed. Results showed that there were four main failure stages, which were first contact between FSP and the plate, partial perforation, full perforation with FSP and plug still intact and lastly separation of FSP and plug. Good agreement was observed between experiment and numerical simulation. [ABSTRACT FROM AUTHOR]
