The behavior of round products under torsion is of interest. For static testing Zwick supplies drives which when used in combination with materials testing machines can apply torque to the specimen and determine the corresponding material properties. It is also possible to superimpose several load axes and test the material according to its use. For fatigue testing under high torque alternating load, frequencies up to over 200 Hz can be achieved in a Vibrophore (HFP) equipped with special test fixtures. Using resonance conditions means that the test is both quick and, due to low power consumption, cost-effective.
