A new testing device has been developed to test the antifatigue abilities of several pressure vessel materials. Crack initiation and propagation through grain boundaries can be seen clearly by the optical microscope and computer multi-media system at the microscopic level. It has been determined that the shear stress plays subtle effects to the first stage of crack initiation. The effects of small defects to fatigue lives are also discussed.
