The Application of Advanced Measurement Techniques and Modelling of Material Plasticity to enhance ballistic toolmarks investigation

该项目旨在通过研究材料组成在发射过程中对子弹底火塑性变形的影响，向不同材料类型的弹道关联迈出关键一步。这将建立一个完全自动化的系统，能够对材料属性中的变量进行建模和补偿，从而增加客观性，并开辟一条加强这种比较系统证据价值的途径。在同一支枪发射了不同材料成分的子弹的情况下，这一点很重要。该项目将确定材料成分在底火地形可变性中所起的作用，并将为真正自动化和客观的弹道关联提供基石

This project aims to take a key step towards ballistic correlation across material types of by investigating the effect that material composition plays in cartridge primer plastic deformation during firing. This will allow for a fully automated system which is able to model and compensate variables in material hproperties, thus increasing objectivity and creating a route into strengthening the evidential value of such comparison systems. This is important in cases where the same gun has fired cartridges of different material composition. The project will identify the role that material composition plays in primer topography variability and will provide the keystone to truly automated and objective ballistic correlation
