Fatigue

Fatigue behavior in fiber composites is measured under a range of loads: as a tensile test, an in-line shear test or at screw or bolt connections.

Different machine types are possible: 

• Servohydraulically dynamic testing machines, which are able to generate variable frequencies and amplitudes under different control modes. 

• Vibrophores, which run at constant frequency in sine-loading. This can be a very affordable type of test for thin-walled specimens, for which adequate heat dissipation is guaranteed.
