Influence of impact velocity and impact attack angle of bullets on damage of human tissue surrogate -- ballistic gelatin.

Purpose: Terminal performance of a bullet in human body is critical for the treatment of gunshot injury and optimization of bullet design. The effects of the impact velocity (v) and the impact attack angle (δ) of the bullet on its terminal performance was investigated, using a new evaluation method (called expansion method) based on the expansion of cracks and the permanent cavity wall in ballistic gelatin.

Methods: Ballistic gelatin was used to simulate human body.
