✦ Synopsis


This paper deals with the identification of a single defect in a discrete spring-mass or beam-like system by measurements of damage-induced shifts in resonance frequencies and antiresonance frequencies. For initially uniform discrete systems, it is shown how the measurement of an appropriate set of frequencies and antiresonances permits unique identification of the damage. The theoretical results are confirmed by comparison with numerical and experimental tests.

This paper proposes a novel approach for nonlinearity detection in vibrating systems. The approach is developed based on a new concept recently proposed by the author known as nonlinear output frequency response functions (NOFRFs) and the properties of the NOFRFs for nonlinear systems with multiple
