Cyclic bending fatigue, measurement

Apparatus for electrochemical measurements during corrosion fatigue. CF tests can be done using an apparatus designed by the Continental Oil Company, as shown in Figure 6.52.110,111 The polarization potential and current can be controlled for the four samples tests at the same time. The apparatus consists of a Monel tank in which four specimens are subjected to cyclic bending. The preliminary step in the experiment is to determine the displacement caused by the desired applied load. The exact stresses are then determined with the use of strain gages.
