This paper is concerned with dynamic hardening equations of metallic materials with various crystalline structures. Dynamic hardening equations reported have been investigated using the dynamic hardening characteristics of three kinds of materials: 4340Steel (BCC); OFHC (FCC); and Ti6Al4V (HCP). Dynamic hardening characteristics of each material have been obtained by uniaxial tensile tests and SHPB tests. Several existing models have been constructed and evaluated for Johnson-Cook model, Zerilli-Armstrong model, Preston-Tonks-Wallace model, modified Johnson-Cook model, and modified Khan-Huang model using test results of three materials. The most applicable equation for each material has been suggested by comparison of constructed results.
