| Abstract: | The modal synthesis technique and small parameter method for eigenvalue groups are-used to analyse the normal mode localization phenomena in the realistic mistimed bladed-disc assemblies. The possibility of occurrance of localization in the realistic bladed-disc assembly is rigorously demonstrated. |
