Abstract

This chapter will introduce the concepts of Strain modal analysis, Strain frequency response function (SFRF), and strain mode shapes. The basic theory for strain-based modal analysis will be presented, using a test-based perspective. The similarities and differences between displacement-based modal analysis and strain-based modal analysis and their formulations will be shown, and the unique characteristics of strain modal analysis will be highlighted. Finally, an experimental example will be presented, where a strain-based experimental modal analysis is carried out on a helicopter blade.
