This report summarizes a study on theoretical and experimental investigations on the strength of thickwalled cylindrical pressure vessels. Most of the available theories@ numbering 21@ are reviewed and classified into four groups (see Table 1). Predictions of maximum pressures by these theories were determined@ based upon tensile properties@ for all the experimental results that could be found in the literature. Maximum pressure values on about 150 thick-walled cylindrical specimens were compared with values predicted by 21 theories or formulas. Pour theories were found to be equally accurate for predieting the maximum pressures. These theories gave +/- 7% average deviations considering all the experimental results. Of the four theories@ the one proposed by the writers in eq 19 of Reference 3 is recommended. The basis for this recommendation is that it is simpler to use than the other acceptable theories. If less accuracy is acceptable@ a simpler approximate equation@ eq 20 of Reference 3@ can be used. This latter equation is based on the ??egoing recommended theory by the writers.
