This work intends to present a novel numerical approach for carrying out virtual Vibration Correlation Technique (VCT) in unstiffened and stiffened structures subjected to mechanical and thermal loadings in order to predict the buckling load, to characterize the natural frequencies variation for progressively increasing loads, and to provide a verification of the experimental VCT results.
