| Summary |
"This experimental investigation was conducted to study the stability of filled cylindrical shell columns. Two kinds of filler materials, flower clay (florist clay) and silica sand, were investigated. The cylindrical shells were made of 2024-T3 Reynolds aluminum tubing. Uniaxial compressive loading was applied directly to the filler materials through two loading rams, one at each end of the cylinder, (no loading was applied directly to the shell). Tests for investigating the load transmitting characteristics of the filler materials were performed, and the states of the stresses existing in the cylindrical shells were then obtained. The buckling formula for thin-walled cylindrical shells under internal hydrostatic pressure was compared with the experimental results of the cylinders filled with clay. The theory for thin-walled cylinders subjected to direct uniaxial compressive loading on the shells was compared with the results for the sand filled cylinders. It was necessary to introduce a reduction factor for effective length when sand was used the filler material. The tangent modulus formula was chosen to predict the buckling load of the filled cylinders beyond the elastic range of the material. The experimental results were found to be in good agreement with the theoretically predicted curves. Comparisons of the theoretical and experimental buckling loads are given graphically as functions of the length and the reciprocal of the square of the length"--Abstract, leaves ii-iii. |
