Abstract
Method for testing a sample (1) under combined rotational bending and torsion loading comprises rotating the sample, applying a torsional load using two torsional torques and bending the sample. An independent claim is also included for a device for carrying out the testing method comprising clamping devices (2) rotated using electric motors (4) to tension the sample and a power unit for moving the clamping devices from an aligned position. Preferred Features: The electric motors are servo motors. Each motor is equipped with an encoder (8) with torque measuring units (5) arranged between the motors to feed measuring data to a controller.
