“…In addition to the conducted case studies, innovations have also been proposed in performing the experiments. Wait et al proposed merging impedance measurement methods with lamb waves (Wait, et al, 2005) and An and Sohn (An & Sohn, 2012) asserted to improved efficiency of impedance measurements while using guided ultrasonic waves. Mascarenas et al (Mascarenas, et al, 2009) suggested a new setup for impedance method which made use of wireless data-collection equipment.…”

Bolted structures are widely utilized in industrial structures and equipment due to the numerous advantages they possess. However, the use of bolts in these structures by itself can cause considerable flaws or damages. One of the major reasons of flaw in such structures is looseness. Since the looseness is initiated with a reduction in the axial force, measurement and estimation of this force can contribute to a healthy performance of the structure. The methods used to measure axial force of bolts are divided into two: those which measure or estimate the force directly and those which, by controlling physical parameters, do this indirectly. Ba-sed on this categorization, this paper examines over 16 methods used for evaluation of axial force of bolted structures, and presents their theoretical bases, drawbacks and advantages, with the litera-ture on each method being discussed separately. Finally, the met-hods are compared and the most important criteria in selecting the methods are introduced.

“…Structural health monitoring (SHM) has made significant advances in the past decades [1][2][3][4][5][6][7][8]. Monitoring of refractories, which are widely used in furnace, iron, and steel industries due to their ability to gain strength rapidly and to withstand aggressive environments and high temperature [9], receives increasing attention [10][11][12][13].…”

Damage Detection of Refractory Based on Principle Component Analysis and Gaussian Mixture Model

et al. 2018

Acoustic emission (AE) technique is a common approach to identify the damage of the refractories; however, there is a complex problem since there are as many as fifteen involved parameters, which calls for effective data processing and classification algorithms to reduce the level of complexity. In this paper, experiments involving three-point bending tests of refractories were conducted and AE signals were collected. A new data processing method of merging the similar parameters in the description of the damage and reducing the dimension was developed. By means of the principle component analysis (PCA) for dimension reduction, the fifteen related parameters can be reduced to two parameters. The parameters were the linear combinations of the fifteen original parameters and taken as the indexes for damage classification. Based on the proposed approach, the Gaussian mixture model was integrated with the Bayesian information criterion to group the AE signals into two damage categories, which accounted for 99% of all damage. Electronic microscope scanning of the refractories verified the two types of damage.

We propose a structural health monitoring (SHM) paradigm based on the simultaneous use of ultrasounds and electromechanical impedance (EMI) to monitor waveguides. Methods based on the propagation of guided ultrasonic waves (GUWs) are increasingly used in all those SHM applications that benefit from built-in transduction, moderately large inspection ranges, and high sensitivity to small flaws. Meantime, impedance-based SHM promises to adequately assess locally the structural integrity of simple waveguides and complex structures such as bolted connections. As both methods utilize piezoelectric transducers bonded or embedded to the structure of interest, this paper describes a unified SHM paradigm where pulse-echo and pitch-catch GUWs as well as EMI are employed simultaneously and are driven by the same sensing/hardware/software. We assess the feasibility of this unified system by monitoring a large flat aluminum plate with two transducers. Damage is simulated by adding small masses to the plate. The results demonstrate that the proposed system is robust and can be developed further to address the challenges associated with the SHM of complex structures
