Abstrakt: A simple device that provides control for constant true strain rate compression (or tension) tests in closed-loop servohydraulic testing machines is described. In the present system, it has been used at strain rates up to 20 s−1. Intended for use in hot working studies, the device allows for single-stroke, change-of-rate, and interrupted sequential tests. In the last of these, interruption times as low as 10 to 20 ms may be achieved.
