This paper utilizes theoretical physics of explosion and collision, combined with experimental explosions and analysis of samples collected in the scene to determine high speed deformation mechanism and failure characteristics of the case for post blast crime scene investigations. In this study, the author uses the methods of scanning electron microscopy (SEM) and metallography to analyze the failure surface morphology of the explosive device case. The obtained results presented in this paper was generalized and typicalized for use in investigating cases involving explosive device.
