This Annual Report of the Ship Structure Committee to the convening authority, the Secretary of the Treasury, covering the activities of the Committee and its affiliated research groups for the year ending May 1, 1961. Technical portions of this report are a continuation of the series of technical progress reports that began with the publication in 1946 of the Final Report of the Ship Structure Committee's predecessor, the Board to Investigate the Design and Methods of Construction of Welded Steel Merchant Vessels. (Author).
The report is arranged in four parts under the general subjects of Design, Fabrication, Materials, and Statistics. Under the first, Design, is recorded confirmation of theoretical formulas for the bending of the hull girder of a ship and demonstration by laboratory tests of the improvements to be gained by relatively simple changes in desgn details. The second part, on Materials summarizes the continuation of the basic work on steel hull plate, looking toward an understanding of the fundamental reasons for brittle fracture, and shows the progress being made toward improvements in specifications in an effort to lower the incidence of fractures. Methods of Fabrication, the third part, summarizes the effect of certain fabrication practices on structural performance. In the fourth part cumulative statistical data on ship casualties are brought up to date.
