“…For the purpose of fully utilized mode information, Kaouk and Zimmerman [14][15][16] defined the residual mode equation for damage detection based on mode information of structure, which can accomplish the dual tasks of determining the damage location and solving the damage situation effectively. is kind of damage detection method has received the widespread attention over the last decade [17][18][19][20][21]. ere exists a common obstacle in the aforementioned detection methods, which is to obtain higher order of structural modal shapes.…”

“…Sipple et al [24] proposed a new FE model updating method that uses numerical sensitivity instead of analytical sensitivity to solve inverse problems, which does not need model reduction and data extension, and has good robustness, stability and fault tolerance; Weng et al [25] proposed a new iterative substructuring method to accurately obtain the characteristic solution and characteristic sensitivity of the structure, which is suitable for model updating of large and complex structures; Jiang et al [26] expressed the thermal dependent elastic constants and thermal expansion coefficients as intermediate function by temperature independent variables, and used the perturbation method to calculate the sensitivity for parameter identification; On the basis of the basic concept of unconstrained optimization problem and three regularization solutions, Mohammad et al [27] proposed a novel sensitivity based FE model updating method, and simultaneously updated the element mass matrix and stiffness matrix of the FE model; Esfandiari et al [28] proposed a FE model updating method using incomplete strain data in frequency domain to detect variations in stiffness and mass parameters. The common sensitivity analysis methods using FRFs are the finite difference method [29] or the combined approximations (CAs) method [30]. These methods are based on obtaining the stiffness matrix, damping matrix, and mass matrix of the structures.…”

“…One important group of FEM updating techniques is the perturbation methods (also known as the sensitivity methods). In last few decades, the perturbation methods have been widely used in model updating, [1][2][3][4][5] damage detection, [6][7][8][9][10][11][12][13] structural reanalysis, [14][15][16][17][18][19][20] vibration control, [21][22][23][24][25] nonlinear mechanics, [26][27][28][29][30] and so on. The traditional perturbation techniques are all the linear approximation methods based on the series expansion (Taylor series or Neumann series).…”
