CAUSES OF CLEAVAGE FRACTURE IN SHIP PLATE: FLAT PLATE TESTS AND ADDITIONAL TESTS ON LARGE TUBES

The materials used in this investigation were three lots of semi-killed hull quality steels, one lot of nickel alloy, one lot of fully-killed, and one lot of fully-killed quenched and drawn steel. The specimens used in the principal program were 3/4 inch thick plates containing a narrow transverse slot having a length equal to one fourth of the specimen width. These were tested in tension in widths ranging from 12 inches to 108 inches. Tests were made at each of a number of temperatures in order to determine the temperature at which the mode of failure changed from shear to cleavage type. In the tests, observations were made of the following: the maximum load, load at development of cracks, fracture load, energy absorbed to maximum load, mode of fracture, strain distribution over the faces of plates and thickness reductions near the lines of fracture.
