Abstract

Theoretical methods for obtaining the complete stress analysis of a pressurized, stiffened circular cylinder of special geometry are presented. In certain limiting cases, the exact solutions are tractable, but in general the solutions lead to approximate results. There are practical cases for which none of the solutions is applicable. Accompanying the theoretical analysis is a short experimental program consisting of the strain gage instrumentation and testing of a Lucite and cellulose acetate model of typical aircraft structural geometry. The results compare favorably with the theoretical analysis.
