I'm currently developing a fatigue test (tension-tension) of thin steel (T-bone) sheets (0.2-0.5mm thickness). The clamping of the specimen should be with screws to cut costs. I already found a...

I want my piezo actuator to give a sinusoidal load as output and thus keep the forces (max, min and mean) constant. To do this I need a close loop control with a load cell I think. However the...
