Identification of nonlinearity in bolted beam using response-controlled testing and force-controlled testing / Khairul Aiman Khairul Anuar ... [et al.]

Nonlinear phenomena such as super-and sub-harmonics and unstable branches in frequency response functions (FRFs) often occur in slender structures, which are common in the aerospace, civil and wind power domains. The widely used methods of linear modal analysis are invalid for the identification of...
