A vibration correlation, consisting essentially of experimental determination of the frequencies under load and assessment of equivalent elastic restraints, developed earlier for stringer-stiffened shells on laboratory-tpye end rings, has been extended to realistic boundary conditions. Six shells with end conditions, simulating typical missile joints, have been tested and analyzed. 'Lumping' of end effects has been studied and results have been compared with tests of similar shells on laboratory-type end rings with prescribed load eccentricity. A method for detection of load eccentricity from vibration tests and assessment of equivalent end restraints has been developed. (Jensen)
