Fatigue Crack Growth in Aluminum Alloy 5083-0 Thick Plate and Welds for Liquefied Natural Gas Tanks

Source

Data are presented on fatigue crack growth rates in thick plate of aluminum alloy 5083-0 for spherical liquefied natural gas cargo tanks. The investigation included: (1) determination of fatigue crack growth rates at room temperature and -320°F; (2) comparison of fatigue crack growth in welds with that in parent material; (3) establishment of the rate and direction of growth of surface flaws under tension and combined tension and bending; and (4) comparison of the rate of growth of surface flaws in plates under spectrum loading with calculated rates based on data from constant amplitude loading of compact tension specimens.
