Vibration-based Damage Identification Methods: A Review and Comparative Study

Abstract: A comprehensive review on modal parameter-based damage identification methods for beam-or plate-type structures is presented, and the damage identification algorithms in terms of signal processing are particularly emphasized. Based on the vibration features, the damage identification methods are classified into four major categories: natural frequency-based methods, mode shape-based methods, curvature mode shape-based methods, and methods using both mode shapes and frequencies, and their merits and drawbacks a… Show more

“…Compared to natural frequency-based methods, mode shape-based methods have the significant advantage of containing information that makes them more sensitive to local damages. They are also less affected by environmental effects such as temperature [5]. However, the disadvantage of the method is that many sensors are typically required to measure the mode shapes accurately and base line data from an experimental test on the intact structure (or an accurate structural model of the intact structure) is also necessary, but often unfeasible.…”

“…A number of authors have published reviews on the most common vibration-based condition monitoring techniques [2][3][4][5]. Broadly speaking these methods can be categorized as: (i) natural frequency based methods, (ii) mode shape based methods and (iii) curvature based methods.…”

“…Built-in SHM system capable of detecting and quantifying damage would increase the operational safety and reliability, reduce the number of unscheduled repairs, and bring down overall maintenance costs. SHM Methods SHM methods can be either vibration based [2] [3]; or wave based [4] [5] [6]. Wave-based SHM (aka, acoustoultrasonics) works in both passive and active modes.…”

“…In the vibration-based detection methods, the damage can be detected through modifications in the linear response (modal parameters) or by the occurrence of nonlinear effects [2][3][4]. A detailed review of the previous researches on the vibration-based detection methods are given in [5][6][7]. Cao et al [8] has shown that the damping is the least applied dynamic parameters for the damage identification, because of the difficulty involved in traditional measurement.…”
