ABSTRACT: Available theories and test data on buckling of curved plates and shells are reviewed. The test data for torsion and external-pressure loadings are correlated in terms of linear buckling theories for both the elastic and inelastic ranges. The cases which exhibit a marked disagreement between linear theory and test data have been analyzed by a unified semi-empirical approach which is satisfactory for analysis and design purposes.

ABSTRACT: Results have been collected on studies relating the stability load of a structure to stiffness and natural frequency. Additional experimentation has been done to include effects of residual stresses and the major portion of this paper is devoted to a discussion of these studies. Finally, further examinations have been made of recent theories to relate stability load, stiffness, frequency and residual stress. The results have been reported here in order to reveal the range of relationships that can be found among these four structural features, and to demonstrate a reasonably sound basis for non-destructive testing procedures to determine residual stresses and structural stability. Hopefully, it also will stimulate further research in this hitherto neglected area.
