Abstract:

Six acrylic resin cellular shells were tested under external hydrostatic pressure to determine the effects of joints between individual shell structure components and the effects of bonding on cellular shell stability. When the shell stiffeners were restrained from moving laterally, the location of joints and the degree of bonding did not affect the general elastic stability enough to cause failure by elastic buckling. All shells failed by material yielding except the one in which the stiffeners were norained from moving laterally. However, the distribution of stresses and strains on the other shell surfaces was considerably influenced by the location of joints and the degree of bonding. The shell stresses were calculated by Pulos and Mehtas formulas and compared with the experimentally determined stresses. The calculated and exper imental values agreed within 15 per cent except for the principal axial stresses on the shell facings at the stiffeners. Author
