Feasibility of speckle tracking in optical coherence tomography (OCT) based on digital image correlation (DIC) is discussed in the context of elastography problems. Specifics of applying DIC methods to OCT, compared to processing of photographic images in mechanical engineering applications, are emphasized and main complications are pointed out. Analytical arguments are augmented by accurate nu...

The present work shows the material flow analysis in indentation by the numerical two dimensional Finite Elements (FEM) method and the experimental two-dimensional Digital Image Correlation (DIC) method. To achieve deep indentation without cracking, a ductile material, 99% tin, is used. The results obtained from the DIC technique depend predominantly on the pattern conferred to the samples. Due...

Artificial Intelligence (AI) technology has quickly developed under the mighty computing power of computers. At this stage, there are many mature non-destructive testing methods in civil engineering, but they generally only suitable for simple structures and evident damage characteristics. Therefore, it’s necessary us to investigate identification wharf concrete deep learning digital image tech...

The quasistatic failure of composite-aluminium bolted joints is investigated experimentally using the stereo Digital Image Correlation (DIC) technique. Single-shear, two-bolt lap made carbon fibre reinforced polymer (CFRP) laminates and aluminium plates are subjected to tensile load while being monitored stereo-DIC. measured displacements processed by removing outliers Grubbs test reducing nois...

High-efficiency and high-accuracy deformation analysis using digital image correlation (DIC) has become increasingly important in recent years, considering the ongoing trend of using higher resolution digital cameras and common requirement of processing a large sequence of images recorded in a dynamic testing. In this work, to eliminate the redundant computations involved in conventional DIC me...

The fracture toughness at the bi-material interface of layered test pieces is determined using digital image correlation (DIC) as part dynamic shear tests. High-strain-rate tests are conducted on a three-layered bonded piece comprising central aluminum layer with PMMA resin layers. When crack sufficiently shorter than bonding length, mode II appears aluminum–PMMA interface; otherwise, I and fra...

Digital image correlation (DIC) has become an industry standard to retrieve accurate displacement and strain measurement in tensile testing other material characterization. Though traditional DIC offers a high precision estimation of deformation for general cases, the prediction becomes unstable at large or when speckle patterns start tear. In addition, requires long computation time often prod...
