The largest discrepancies occurred at the intersection of the shell 

 and web where the fillet was located. This fillet [Figure 1] was incor- 

 porated to reduce the effects of shear and possible stress concentrations 

 due to undercutting or voids that could have developed during fabrication. 

 Observation of the experimental strains suggested that a portion of the 

 fillet acted as a stiffener. This effect is less noticeable or negligible 

 on the two models with longer bay lengths. 



CONCLUSION 



Theoretical analysis as given in Reference 2 will adequately predict 

 the elastic axisymmetric behavior in web-stiffened cylindrical sandwich 

 shells subjected to hydrostatic pressure.
