CORROSION FATIGUE INITIATED BY OCEAN WAVES

Test results on marine platforms show the average number of cycles in each stress range can be calculated from wave parameters (height and period) and a wave distribution function. For low-cycle bending fatigue of 1018 steel in stress loading by ocean waves, (1) fatigue life is best represented by the total number of cycles in the absence of complete stress-strain information for each load cycle, (2) the fatigue life decreases linearly with increased maximum deflection (strain), and (3) corrosion decreases the fatigue life by approximately 50%.
