The paper addresses a relevant subject in structural health monitoring for civil engineering applications such as bridges or other large structures. Experimental laboratory program on the accuracy and precision of remote displacement measurements was reported. Could an onboard optical camera Total Station (Image-Assisted (IATS) Leica Nova) be exploited to integrate measurement techniques even t...

Digital image correlation (DIC) relies on the visible surface features of a specimen to measure deformation. When the specimen itself has little to no visible features, a pattern is applied to the surface which deforms with the specimen and acts as artificial surface features. Since recent pattern application methods, e.g., micro-stamping [1] and lithography [2] allow for the application of hig...

The venerable digital image correlation (DIC) technique relies on a series of digital images to obtain the incremental displacement and strain field on the surface of a specimen. In a standard DIC procedure, the image recording system and the object are kept in the same medium i.e. images are taken while the object is deforming in air. There is a growing need, however, to extend the use of DIC ...

The effect of short fiber reinforcements on the mechanical properties of cement has been examined using a splitting tensile - digital image correlation (DIC) measurement method. Three short fiber reinforcement materials have been used in this study: fiberglass, nylon, and polypropylene. The method outlined provides a simple experimental setup that can be used to evaluate the ultimate tensile st...

Abstract Digital Image Correlation technique (DIC) is a non-contact optical method for rapid structural health monitoring of critical infrastructure. DIC used to extract Moment (M) – Curvature (κ) relationships using random speckle patterns. The pattern evaluated 2D measurements and shows an improved correlation with conventional measurements. Characteristics patterns are quantified their appli...

Background: In the Clean Sky 2 project DIMES, cyclic loading of a section an A320 wing with pre-existing damage was carried out. Methods: We present Digital Image Correlation (DIC) prototype system to monitor crack propagation in aircraft wing. This includes mount for easy installation and adjustment confined space. ...

Digital image correlation (DIC) has become a well-established approach for the calculation of full-field displacement and strains within the field of experimental mechanics. Since their introduction, DIC methods have been relying on only two images to measure the displacements and strains that materials undergo under load. It can be foreseen that the use of additional image information for the ...

BACKGROUND Determining the mechanical behaviour of tendon and ligamentous tissue remains challenging, as it is anisotropic, non-linear and inhomogeneous in nature. METHODS In this study, three-dimensional (3D) digital image correlation (DIC) was adopted to examine the strain distribution in the human Achilles tendon. Therefore, 6 fresh frozen human Achilles tendon specimens were mounted in a ...
