高应变率下材料力学行为的研究在汽车碰撞试验和高速切削等工程应用中越来越受到重视。目前的高应变率技术，如分离式霍普金森杆不能提供可靠的实验数据，材料模型识别，特别是在低应变。本文采用惯性冲击试验、超高速成像和虚拟场法对铝合金的弹塑性性能进行了识别。
The study of the mechanical behavior of materials at high strain rates is of growing interest in many engineering applications such as automotive crash-tests and high speed machining. Current high strain rate techniques such as the split-Hopkinson bar fail to provide reliable experimental data for material model identification, particularly at low strains. In the paper, inertial impact tests, ultra high speed imaging, and the virtual fields method are used to identify the elasto-plastic properties of aluminum.
