“…Three different types of damage in laminated composite beams have been successfully detected by the GFD [38,40]. It should be pointed out that the GFD bears no conventional physical meaning as compared to the FD, and it only serves as an indicator of damage.…”

“…Recently, Qiao and his coworkers (i.e., Qiao et al, Hamey et al, Lestari and Qiao, Lestari et al [40,[71][72][73][74]) conducted a series of studies on using strain mode shapes measured from surface-bonded piezoelectric sensors to identify various damage in composite beam or plate structures. Hamey et al [71] evaluated several damage detection algorithms in carbon/epoxy composite beams with several possible damage configurations using directly measured curvature mode shape (strain mode shape).…”

“…Qiao et al [40] evaluated three response-based damage detection algorithms (i.e., simplified GSM, GFD, and SEM) for composite laminated plates using the data acquired from two measurement systems (i.e., a surface-bonded piezoelectric (PVDF) sensor system and a scanning laser vibrometer (SLV) system). From the damage detection outcomes, it is observed that the non-contact SLV system proves to be more convenient and effective, and it is capable of scanning high-density mode shape data over the entire plate specimens; while the PVDF system, in which the curvature mode shapes are directly acquired, exhibits good sensitivity to damage, and it is capable of performing onboard and in situ health monitoring.…”

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 are discussed. It is observed that most mode shape-based and curvature mode shape-based methods only focus on damage localization. In order to precisely locate the damage, the mode shape-based methods have to rely on optimization algorithms or signal processing techniques; while the curvature mode shape-based methods are in general a very effective type of damage localization algorithms. As an implementation, a comparative study of five extensively-used damage detection algorithms for beam-type structures is conducted to evaluate and demonstrate the validity and effectiveness of the signal processing algorithms. This brief review aims to help the readers in identifying starting points for research in vibration-based damage identification and structural health monitoring and guides researchers and practitioners in better implementing available damage identification algorithms and signal processing methods for beam-or plate-type structures.

“…The damage can be detected when the measured and simulated dynamic parameter deviates appreciably from the value expected for a healthy structure. Many studies show how these parameters produce satisfactory damage diagnoses with an acceptable level of accuracy [3][4][5]. However the modal parameters are linked to the out of plane displacement, so that the behaviour of the structure is well known only in one direction.…”

Abstract. The investigation of damage induced by dynamic events is since many years of central interest especially to increase safety and security of all means of transportation. The use of integrated full-field optical methods and FEM analysis gives good results in investigating damage produced after impact. In this paper a methodology for assessing impact damage using both simulation and experimentation will be presented. The methodology considers the effect of the defect presence on different parameters (e.g. geometrical parameters, strain field, dynamic parameters). Although a number of possible approaches in providing FEM and measurement results are being investigated, a general procedure to compare the data has been identified and includes the possibility of using reduced or decomposed data for the comparison of results from experimentation and simulation.

Abstract. Identifying non-uniform cracks in plates is a challenging problem worthy of exploration. 2D modal curvature is often utilized to detect damage in plates, but its capability to precisely identify non-uniform cracks has not been resolved well, largely due to two noticeable deficiencies, lack of sensitivity to damage and susceptibility to noise interference. With this concern, this study ameliorates the 2D modal curvature using the wavelet transform, whereby the wavelet 2D modal curvature is constructed. Damage features extracted from the wavelet 2D modal curvature can be employed to identify non-uniform cracks in plates. This wavelet 2D modal curvature enjoys the multiscale analysis characteristics introduced by the wavelet transform, leading to synchronous extraction of damage features and elimination of noise interference. These features endow the wavelet 2D modal curvature with the capability to identify non-uniform cracks under noisy conditions. The performance of the wavelet 2D modal curvature is verified by damage detection in a plate with a non-uniform crack. The results show the wavelet 2D modal curvature can effectively identify non-uniform cracks in plates under noisy conditions.
