Application of DIC Technique to Concrete—Study on Objectivity of Measured Surface Displacements

Relationship between vortex structures and shear localization in 3D granular specimens based on combined DEM and Helmholtz–Hodge decomposition

“…DIC is a non-contact experimental technique to measure surface displacements on a deforming solid [54]. In order to determine the vortices in the form of a rotational motion of several grains around its central point, the displacement fluctuation vectors of small clusters of grains were calculated from the mean displacement vector field.…”

“…The experimental detection's method was however based on displacement fluctuations of small clusters of grains (not single grains) and was strongly limited by the accuracy of DIC. Moreover DIC is sensitive to the assumed subset size and image length resolution [54].…”

Multi-Criteria Optimisation of Liquid Cargo Transport According to Linguistic Approach to the Route Selection Task

“…One of the important thing in these processes are the decision about materials, ship equipment, i.e., navigational, electrical or handling [14], and detailed construction solution. This area concerns research not only on a new composite structure for a ship hull what should increase structural safety during a collision [18], [21]. Also, it concerns the processing technologies of various parts of the ship to reduce the impact of adverse factors [7], [9], [21].…”

Moreover, the significant field of interest is also the effectiveness and fuel consumption of ship engines [13].…”

Fracture process zone and tensile behavior of blended binders containing limestone powder

“…While several experimental techniques such as high speed photography [12], acoustic emission [13][14][15], scanning electron microscopy (SEM) [16][17][18][19], and laser-speckle interferometry [20,21] have been used to investigate FPZ in concretes, this study employs a non-contact digital image correlation (DIC)-based speckle-tracking method [10,[22][23][24][25][26][27][28] to assess the surface displacements and strains, and thus the width of the FPZ. The presence of soft(er) limestone particles and ductile clay phase (from metakaolin), which improves the fracture performance of multiple-material binders through improved inelastic energy dissipation [10], influences the FPZ, which is explored in detail.…”
