Buckling of Cylindrical Shells with Axisymmetric Toroidal Initial Imperfections.

摘要

Some recent advances in thin shell buckling theory which tend to explain the discrepancy between experiment and theory are reviewed. The results of a digital computer study to determine the effect of three discrete axisymmetric imperfections on the buckling load of two specific circular cylindrical shells are presented and discussed. The shells were 40inches long with wall thicknesses of 0.02inch and radii of five and ten inches. Initial imperfection amplitudes considered were 0.005, 0.01and 0.02inch. (Autho)
