The experimental data were&nbsp;obtained from a laminate beam. The routine uses robust statistics and analysis was done in a&nbsp;data set from healthy and damaged structure. This technique has being developed for FRFs&nbsp;at high frequency range, which have showed to be more sensitive to small damages. In this work are presented results for detection algorithm in different frequency ranges, effectiveness&nbsp;of coherence signal applied to measurement dataset, FRF signal resolution, RSVD parameters&nbsp;and computational costs.</p> ER -
