It is well understood that internal defects within crystalline explosives can promote the formation of hot-spots under shock loading, thereby sensitising them to impact. Conversely, defect-free crystalline explosives are much less sensitive to initiation. The threshold quantity of different types of defect, and their influence on initiation is much less well understood. This PhD opportunity will investigate non-destructive analysis to characterise crystalline defect, and relate these to initiation by explosively-generated shock waves.

众所周知，结晶炸药的内部缺陷在冲击载荷下会促进热点的形成，从而使其对冲击敏感。相反，无缺陷水晶炸药对起爆的敏感性要低得多。不同类型缺陷的阈值及其对起裂的影响还不太清楚。这个博士机会将研究非破坏性分析，以表征晶体缺陷，并将这些与爆炸产生的冲击波引发联系起来。
