One approach to correlation between structural damage and dynamic response of the cantilever

This paper presents one approach in damage detection using frequency response functions data. The method based on damage detection and relative quantification indicator is used, in order to detect, locate and quantify the damage of the cantilever. Experimental modal investigation was conducted on the cantilever beam using hammer excitation and “roving hammer” method of modal testing. Proposed damage detection method shows good performance even for the hammer excitation and one response transducer available, which is important considering the practical implementation of the method in the frugally equipped laboratories.
