- Summary
-
The effect of ring size on the buckling of truncated isotropic conical shells supported at the ends by rings and subjected to hydrostatic- or lateral pressure loadings has been studied. Results were obtained from an approximate theory based on Donnell-type shell theory and a membrane prestress state. For a given shell geometry, the ring properties were varied to determine the smallest ring required to provide the equivalent of essentially clamped support. For a particular application, this procedure yielded the minimum mass of the shell-ring configuration. A nondimensional stiffness parameter was determined which correlated, in general, the results for the entire range of ring and shell geometries considered. Approximate formulas are presented for the preliminary design of rings with both closed (circular and square) and open (I and Z) cross sections.
