Abstract:

A cyclic test with a 1-minute hold at maximum pressure was conducted on a ring-stiffened, glass-reinforced plastic cylinder. The model was subjected to a pressure variation from 200 to 6700 psi, which corresponds to one-half the collapse pressure of a model with similar geometry tested under short term hydrostatic loading. At the conclusion of 8626 cycles, no apparent loss in structural integrity was noted. The model was then loaded to a hydrostatic pressure of integrity was noted. The model was then loaded to a hydrostatic pressure of 14,000 psi without catastrophic failure however, inspection of the model revealed crazing on the inside surface of the shell in regions corresponding to maximum longitudinal and circumferential stresses.
