摘要

The purpose of this study was to implement dynamic loading under the standardised testing conditions of the Charpy test (AS 1544.2-2017) using a drop tower testing equipment. The results were compared to Charpy tests via statistics and cumulative data generation. The study shows that the drop tower reveals the instantaneous rate of deformation, yield points, peak and mean forces during the transfer of impact energy, failure load and effects on all the aforementioned factors upon changing strain rate. These results provide a more comprehensive insight into internal material properties such as the crystal structure and trends such as the ductile to brittle transition of steel.
