From "Design and fabrication of a ring-stiffened graphite-epoxy corrugated cylindrical shell" by Read Johnson, Jr., NASA CR-3026, August 1978
PARTIAL SUMMARY:
The objectives of the program reported here are to advance lightweight composite shell design technology and evaluate appropriate design and analysis procedures for lightweight composite shells that must satisfy buckling requirements. To accomplish those objectives the primary effort was to design and fabricate a graphite-epoxy cylindrical shell 3.05m (10 ft) in diameter by 3.05 m long for evaluation in shell bending tests to be conducted by the Structures and Dynamics Division of the NASA Langley Research Center. Through such tests the use of advanced composite materials will be evaluated for structural applications in future space missions such as those that involve spacecraft and structural assemblies to be used in geosynchronous missions. Spacecraft for such missions will require ultralightweight structures to achieve maximum payloads...
This large test rig at NASA Langley Research Center can apply overall bending to very large test specimens.
