Statistical analysis of impact parameters of soft nose bullet fired on windowpane.
Proper collection of glass evidence from crime spot is very important for its latter probative values. Glass evidence when properly collected and analyzed becomes a powerful witness and it can speak truth long after the crime. In criminal investigation glass evidence can tell what had happened and when it had happened. In the present study, a statistical regression analysis relationship between thickness of windowpane used as targets by soft nose bullet using.315"/8mm caliber sporting gun made in ordnance factory, India and various associated impact parameters were investigated. The relationship is found to be reasonably linear. The ballistics performance of windowpane has been found to correlate with the shear strength behavior above the elastic limit.
