Book excerpt: Two additional experiments using the single specimen approach described in detail in this report supplement and extend the authors previous research by considering circular cylinders with higher R/t ratios which buckled at a lower percentage of the classical critical load. The shells had R/t ratios of 946 and 1419 and buckled at 43.9 and 24.6 percent of classical, respectively. In all four experiments, 204 tests were conducted. Ranges in test machine extensional stiffness from 589,000 lb/in. to 2400 lb/in. were considered; R/t values ranged from 226-1419 and Pcr /Pcl values from 0.249 to 0.77. L/D ratios were approximately consistant in all cases . The results provide overwhelming evidence that the Tsien criterion is inapplicable in all problems considered. This may be due to the invalidity of the criterion itself or to the inadequacy of the large displacement analysis. The consequences, however, are the same; scatter in experimental results is not due to the influence of test machine rigidity and a new look at the large displacement analysis and the appropriate criterion is needed.

Book excerpt: The inadequacy of small displacement theory of thin shells in explaining the buckling of circular cylindrical shells has been established. Likewise, it has become general belief that an explanation can be given by means of a nonlinear large deflection theory. The current theories lean heavily upon a plausible but arbitrarily chosen energy criterion first given by Tsien, and predict that the initial buckling load should be influenced by the testing machine stiffness. Two experiments described, statistically analyzed, and discussed by the authors in a previous paper revealed that test machine extensional rigidity does not influence the initial failing load. These results were obtained from repeated tests on a single near-perfect aluminum specimen and individual tests on many less perfect steel shells. They had R/t ratios of 313 and 226, respectively, and buckled at 77 and 45 percent of the classical critical load. (Author).

Book excerpt: The report presents the results of two series of tests which were made to investigate the commonly accepted criterion of instability for shell bodies. This criterion, as generally postulated, states that the total potential energy must be the same before and after buckling. It is an analytical consequence of this contention that the critical load at constant end shortening must be greater than at constant stress. Thus, there should be a difference between tests made in rigid and flexible machines. The experiments recorded provide very strong evidence that this is not so. In the research reported, no evidence of machine influence on initial buckling conditions could be found. (Author).
