Experiments were carried out with a new split Hopkins bar apparatus specially designed for the dynamic tensile test of sheet metals of deep drawing quality. The quasi-static and dynamic tensile tests provided stress-strain curves of sheet metals for various strain rates. The five constants in the Johnson-Cook relation of sheet metals such as SPCEN, SPCC and SPRC were determined by experiments and numerical simulation with ABAQUS/Explicit. The constants were used to calculate stress-strain curves of sheet metals with respect to strain rates by the Johnson-Cook relation.
