Abstract : The report contains a description of tests made to determine why ship plates crack in service. The tests were based upon the hypothesis that the cracks begin at points where thee are severe geometrical stress-raisers and that the tendency for the plates to crack increases, for specified geometrical characteristics, with an increase in the notch-sensitivity of the steel. Plates with nominal widths of 72, 48, 24 and 12 inches were tested. The tests were planned to determine: (1) The relative energy-absorbing capacity and strength of plates of the six kinds of steel. (2) The relation between the width of the plates and their strength. (3) The relation between the temperature of the plates and their strength and energy-absorbing capacity. (4) The relation between the type of fracture and energy-absorbing capacity of the plates. (5) The correlation of the V-notch impact test and the wide plate test.
