Abstract
The availability of a Vibration Correlation Technique (VCT) for nondestructive determination of buckling loads of cylindrical shells has obvious advantages. Earlier, a semi-empirical VCT approach has been developed and applied successfully for the prediction of the buckling load of closely stiffened aluminum shells. In the present paper, a possibility to support and improve the estimates of this semi-empirical VCT approach by means of the application of analysis tools is proposed. Two semi-analytical models with different levels of complexity will be used for this purpose. In the two approaches employed, both the nonlinear effect of the static state and the nonlinear effect of the geometric imperfections are represented. These two methods form the basis of an extension of the existing semi-empirical Vibration Correlation Technique for shells, to a VCT in which vibration measurements and analysis tools are combined. In this paper, the capability of the analysis tools which can be used to improve the VCT is illustrated.
