COMPLEX BULLET INTERACTIONS: AN EXPERIMENTAL STUDY OF UPPER LEG INJURIES TO DEMONSTRATE BALLISTIC MODELLING IN MULTIPART LIMB STRUCTURES

摘要

Significant work has been undertaken characterising gelatine as a tissue simulant forballistic testing, the human body however also includes skin and bone within the system.This paper investigated the effect of including bone and skin simulants to represent the thighon bullet trajectory and temporary cavity. Entry and exit wounds were also compared. 9x19mm FMJ pistol and 7.62x51 mm NATO rifle ammunition is used to complete firings at aseries of targets including gelatine block and bone-gelatine models with a number of skinsimulants. Shots are fired with trajectories that pass through the bone and close to the bonefor comparison. All firings were recorded with high speed video allowing analysis of thetemporary cavity. The results from the firings are presented and discussed. Distincttemporary cavities caused by the presence of bone and skin simulant are described for boththrough and passed bone cases compared to 10% gelatine only blocks.
