✦ Synopsis

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.
