CYCLIC PRESSURE-LOADING TESTS OF A RINGSTIFFENED CYLINDER FABRICATED OF GLASS-FILAMENT REINFORCED PLASTIC.
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.
