Split Hopkinson bar facility for high strain rate testing of materials

无论是能够在爆炸或地震中幸存下来的土木结构，还是能够在碰撞过程中最大限度地减少伤亡的汽车，其设计都需要对动态载荷下的材料响应和失效有最佳的理解。分离式霍普金森杆装置作为测定高应变率下材料性能的最常用技术，将极大地促进合金、聚合物复合材料、泡沫金属和其他新的先进材料的发展，这些材料在抗爆设计、车辆耐撞性和航空航天工业中具有重要的应用。

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.
