Can you provide a link to the journal article?

Perhaps they were doing Harmonic Response analysis. That is where deformation can be calculated vs frequency of the applied load.

It makes no sense to plot deformation vs frequency for a Modal analysis.

Please take the free classes on Modal analysis and Harmonic Response analysis to understand the difference.
