A Digital Image Correlation Technique for Laboratory Structural Tests and Applications: A Systematic Literature Review

Abstract

Digital image correlation (DIC) is an optical technique used to measure surface displacements and strains in materials and structures. This technique has demonstrated significant utility in structural examination and monitoring. This manuscript offers a comprehensive review of the contemporary research and applications that have leveraged the DIC technique in laboratory-based structural tests. The reviewed works encompass a broad spectrum of structural components, such as concrete beams, columns, pillars, masonry walls, infills, composite materials, structural joints, steel beams, slabs, and other structural elements. These investigations have underscored the efficacy of DIC as a metrological instrument for the precise quantification of surface deformation and strain in these structural components. Moreover, the constraints of the DIC technique have been highlighted, especially in scenarios involving extensive or complex test configurations. Notwithstanding these constraints, the effectiveness of the DIC methodology has been validated as a strain measurement instrument, offering numerous benefits such as non-invasive operation, full-field measurement capability, high precision, real-time surveillance, and compatibility with integration into other measurement instruments and methodologies.

Prediction of Residual Compressive Strength after Impact Based on Acoustic Emission Characteristic Parameters

“…Digital Image Correlation (DIC) is an optical method that utilizes image registration techniques to accurately measure two-dimensional and three-dimensional changes in images. This method is commonly used for noncontact, full-field displacement and strain measurements [20].…”

Within the impact energy range of 10 J to 25 J, as the impact energy increased, the loading time required to reach the peak load gradually decreased.…”

Conversion, Prediction, and Application of Strength Parameters for Grouted Reconstructed Rock Mass

“…Ultrasonic testing techniques was employed to gauge the fluctuation of acoustic wave velocity within differently fractured rock masses, unraveling the nexus between rock mass fracture damage and grouting reinforcement (Fathollahy et al 2021). Concurrently, with the incessant evolution of experimental methodologies and technologies, researchers delving into grouted rock masses have also embraced the utilization of digital image correlation (DIC), scanning electron microscopy (SEM), X-ray diffraction (XRD), and other methodologies to scrutinize microstructural attributes (Mousa et al 2023).…”
