general, represent the state of knowledge as it was understood at the 

 time his paper appeared. 



The purpose of this report is to present and discuss in detail some of 

 the physical concepts and mathematical formulations for the stress and 

 buckling of cylindrical hull structures. No attempt will be made to 

 discuss so-called design criteria or even to outline a design procedure 

 because this could possibly infringe on the realm of classified information. 

 Furthermore, it is beyond the scope of this short presentation to give 

 extensive comparisons between experiment and theory, but it will be 

 implied that only those theories and/or empirical formulas will be con- 

 sidered which are finding wide use and which represent the best knowledge 

 of structural analysts at the Model Basin. It is assumed that the readers 

 possess some familiarity with the subject content covered in such courses 

 as advanced strength of materials, theories of elasticity and plates and 

 shells, and differential equations.
