The design of both civil structures that can survive explosions or earthquakes and automobiles that can minimize casualties during crash requires optimum understanding of material response and failure under dynamic loading. As the most commonly used technique for determining material properties under high strain rates, the proposed split Hopkinson bar facility will greatly promote the development of alloys, polymer composites, metal foams and other new advanced materials for important applications, such as in blast-resistant design and vehicle crashworthiness, and in aerospace industry.

能够承受爆炸或地震的土木结构的设计以及能够最大限度地减少碰撞中伤亡的汽车的设计都需要对动态载荷下的材料响应和失效有最佳的了解。作为在高应变率下确定材料性能最常用的技术，拟议的分体霍普金森棒设施将极大地促进合金、聚合物复合材料、金属泡沫和其他重要应用（例如防爆设计）的新型先进材料的发展和车辆耐撞性以及航空航天工业。
