“…The numerical model is used to simulate damage scenarios at various locations in the structure and the corresponding natural frequencies are calculated. Vibration data is then collected from the structure and the damage location/severity is estimated by matching the observed natural frequencies to those calculated by the numerical model [6][7][8]. Salawu [8] presents a review of papers dealing with the detection of structural damage using frequency changes.…”

“…The ordinary natural frequency criteria are Cawley-Adams criterion and damage location assurance criterion (DLAC). Multiple damage location assurance criterion (MDLAC) is an extension of DLAC to detection multiple flaw sites [42]. Frequency response assurance criterion (FRAC), frequency domain assurance criterion (FDAC) [43], global shape correlation (GSC) function and global amplitude correlation (GAC) function are the criteria of FRFs [44].…”

“…Messina et al [10] proposed a correlation coefficient termed the multiple damage location assurance criterion (MDLAC) by introducing two methods of estimating the size of defects in a structure. The method is based on the sensitivity of the frequency of each mode to damage in each location.…”

“…When experimental data on the intact structure is not available, a finite element model is usually adopted to generate the baseline data. Shi et al [30] extended the damage localization method based on multiple damage location assurance criterion (MDLAC) [10] by using incomplete mode shape instead of modal frequency. The two-step damage detection procedure is to preliminarily localize the damage sites by using incomplete measured mode shapes and then to detect the damage site and its extent again by using measured natural frequencies.…”
