Parametric identification of nonlinearity in structural systems using describing function inversion
Method developed for parametric identification of nonlinearity is improved. Restoring force plots obtained from describing function inversion are used. Simulated and experimental case studies are presented for the verification. Identification of multiple nonlinear elements is demonstrated with case studies. Identification of nonlinearity between two coordinates is experimentally demonstrated.
