Paper Abstract

Because a scanning laser vibrometer can perform vibration measurements with a high spatial resolution it is an ideal instrument to accurately locate damage in a structure. In literature different authors successfully used linear vibration measurements to detect faults with the aid of a scanning vibrometer. In this article we will study the feasibility of using nonlinear vibration features to detect and locate damage in a structure. The nonlinearities will be estimated using both classical and a newly developed technique. A comparison of linear and nonlinear damage detection features will be performed on measurements of a cracked plexiglass panel and a delaminated composite plate.
