The salient results of two decades of research into such broad areas as materials, physical and qualification tests, nondestructive testing of welds, stress distribution, data from ships in service, and bending moment determination by models are presented. The brittle fracture phenomenon is attacked from a number of fundamental views: variation of composition and microstructure, prior strain and thermal history, rate of loading, stress intensity and distribution, effect of flaws, and variation of test method. All these bits of research are shown to have contributed to the attainment of an engineering solution. Several of these areas are further discussed. Stress distributions at various geometrical discontinuities are reported as are those arising from temperature gradients. Stress intensities measured on ships in service are presented as are the long-term predictions from these measurements. The effect of mill practice on material performance is discussed. The current effort of developing generalizations from results of specific research is described. The trend of the future, the adaptation of computer to exploit generalizations for analysis of whole systems of structure, is set forth. Finally, a listing of nearly 200 reports is given along with information on how to obtain them from Federal repositories. (Author)
