his monogra])h has been sponsored by The Society of Naval Architects 

 and Marine Engineers and the Sliip Structure Committee. It was prepared under the 

 advisory guidance of a committee appointed jointly by the H-7 Panel of the Hydro- 

 dynamics Committee of The Society of Naval Architects and Marine Engineers, and the 

 Committee on Ship Structural Design of the National Academy of Sciences-National 

 Research Council, which advises the design research program of the interagency Ship 

 Structure Committee. 



Both sponsoring groups have needed a monograph to undertake a critical survey 

 of the state of the art so as to form a basis for the planning of research in this field. M. 

 St. Denis, Ciuiirman of the H-7 Panel, and E. M. MacCutcheon, then a member of the 

 Ship Structure Subcommittee, were instrumental in arranging a meeting of representa- 

 tives of the H-7 Panel and of the Committee on Sliip Structural Design, which led to 

 initiation of this work. 



B. V. Korvin-Kroukovsky had performed fundamental research in the field and 

 was invited by the sponsoring groups to undertake the work of preparing the monograph. 

 He has been assisted by W. Marks of the David Taylor Model Basin in the joint prepa- 

 ration of Section 8 of Chapter 1 and Section 3 of Chapter 3. 



As a result of the lack of complete quantitati\-e data in many areas considered by 

 this monograph, and, indeed, basic disagreement as to exactly what the monograph 

 should cover, some controversy has been raised by preliminary drafts distributed to a few 

 individuals working in these fields. The Advi.sory Committee believes that controversy 

 should not be suppressed and that the publication of this work will encourage research 

 upon which subsequent projects can depend for resolution of these disputed points.
