This paper deals with a tension/compression test of sheet metals considering intermediate strain rates with a hydraulic material testing machine. For the tension/compression test, novel devices are designed to impose a designated tensile pre-strain and to reverse the loading direction. The novel devices have advantages for the load measurement regardless of the fundamental mode of the devices at intermediate strain rates. Tension/compression tests are performed for TRIP980 and TWIP980 steel sheets considering strain rates ranging from 0.001 s−1 to 100 s−1. From the test results, tension/compression hardening behaviors are analyzed with respect to the strain rate.
