This report covers work done during the period of July 1, 1949, to October 15, 1950. This program was requested by the Project Committee and the Committee on Ship Steel to secure a true appraisal of the notched-bead bend test as a test for evaluating performance of ship steels in large welded structures. It was thought that a determination of the fracture mechanism should accomplish this by showing if welding makes the steel in the heat-affected zone of the weld more susceptible to brittle failure or if some feature of the fracture process makes the test unsuited to that purpose. This investigation coves crack initiation and propagation in Kinzel-type specimens made from "Br" and "C" steels. It also covers miscellaneous studies of fracture in Lehigh specimens; in special Kinzel-type specimens taken from "C" steel weldments of the kind being investigated by Case Institute of Technology (SSC Project SR-99), and specimens of a steel containing 0.33 per cent carbon and 0.88 per cent manganese.
