Abstract

In this study an investigation into the effect that medium strain rates have on the mechanical properties of cold drawn mild steel and 304 stainless steel has been carried out using 6 mm diameter cylindrical specimens. The tests were performed using an Instron test machine under a quasi-static strain rate, and a high capacity instrumented falling weight axial impact (IFWI) test rig. The axial load time histories were measured by a load cell connected to each specimen and the deformation time history by a strain gauge attached to each specimen. All the data was acquired by a high-speed data acquisition system at a sampling frequency of 300 kHz. The load histories showed high frequency oscillations and were digitally filtered by using a fourth order low pass Butterworth filter. The results showed that the yield stress and tensile strength of both types of steels increased with an increased rate of strain.
