0 Introduction By SplitHopkinsonBar (SHB: Tension and Compression Test System) test, the mechanical properties of high strain rate materials in the range of 200 ~ 10000s-1 were studied. High strain rates are one of the key features of advanced high-strength steels (AHSS) because most high-strength steels are used in areas prone to impact. IspatInland has embarked on a project to bring a group of AHSS steel to high strains
