Abstract

At the crime spot, crime scene managers /investigating officer are often encounters the shooting through inanimate targets like wall, vehicle, window pane, glass doors, wooden doors etc. The marks of indentation may took place by sharp, blunt instrument or high speed impact like bullet indentations. To analyse source of fracture on various targets by high speed impact, the examination of indentation or hole is most powerful test techniques. In this paper, systematic investigation of deformation and fracture responses in different target materials has been discussed to evaluate critical mechanical parameters with more simplify and high accuracy. At the crime spot, investigating officer does not know the status of holes caused due to blunt or sharp weapons or due to firearms. In present work, an attempt has been made to investigate the behavior of different brittle and non-brittle target materials under bullet impact. Scientific study of behavior of target material under bullet impact can be useful to forensic scientists, investigating agencies/police officers to know the cause behind the fracture of origin.
