MODEL OV-1 



This model represents a one-diameter length of the hull design as 

 proposed by the Bureau of Ships; see Figures 1 and 2a. The design was 

 arrived at by using a modified membrane -type analysis in lieu of a more 

 exact method of determining a suitable geometry and material distribution 

 for the sandwich structure. This membrane -type analysis was used to 

 determine the shell thickness at which hoop yielding would occur at a
