Abstract:

This report describes the dynamic testing machine at NCEL and gives the results of dynamic tests conducted on a chrome-alloy steel. These results are compared with results obtained by other high-speed testing machines. At a strain rate of 2 inches per inch per second, the chrome-alloy steel shows an increase in the upper yield stress of approximately 25 percent compared to the average static value. A general increase in tensile strength between 6 and 7 percent greater than static values is evident with an increase in head velocity. No change in ductility could be detected.
