Utilizing Digital Image Correlation (DIC) in Asphalt Pavement Testing
Journal of Testing and Evaluation, 2017Abstract The digital image correlation (DIC) technique as a displacement and strain measurement method is one of the newest measurement technologies employed in asphalt pavement testing. Although DIC was introduced for material testing in the early 1980s; this technology is not yet being used to its highest potential as a reliable and ...

Digital Image Correlation (DIC)
2021Digital image correlation (DIC) is a full-field non-contacting optical method that can capture the shape, motion, and deformation of solid objects. The basis of the method is the matching of the gray values of points from an image of the surface of an object before and after deformation.

Application of digital image correlation (DIC) to sloshing liquids
Optics and Lasers in Engineering, 2019Abstract Liquid sloshing is one of the major issues for the storage and transportation of liquid such as fuel tanks. This topic has been investigated with numerical simulations or by experimental methods. However, simulations are based on many assumptions and the results sometimes cannot fully describe the actual movements of the liquid inside the ...

Full Blade Digital Image Correlation (DIC) Test Apparatus
2022The objective of this study was to design a Digital Image Correlation (DIC) apparatuscapable of measuring sectional stiffness properties of full scale helicopter blades within preexisting facilities. To do so, this study expanded on previous studies findings that deemed DIC apparatus as an ideal system to measure the strain field over composite blades.

Using Digital Image Correlation (DIC) in Dynamic Punch Tests
Experimental Mechanics, 2014A dynamic punch test in which three dimensional digital image correlation (DIC) is used to measure the deformation of the rear surface of a disk specimen is introduced. Flat, round Ti-6Al-4V disk specimens are clamped to a custom die fixture that is attached to the transmitter bar of a compression split-Hopkinson bar (SHB) apparatus. A tungsten carbide

The application of digital image correlation (DIC) in fatigue experimentation: A review
Fatigue & Fracture of Engineering Materials & Structures, 2022AbstractIn recent years, the use of digital image correlation (DIC) in fatigue experiments has become widespread. It is estimated that ~1000 published works exist that outline fatigue experiments in which DIC is employed for displacement and strain measurement. Of these, ~900 were published in the last 10 years.

Experimental investigation of the tensile test using digital image correlation (DIC) method
Materials Today: Proceedings, 2020Abstract The Digitial Image Correlation (DIC) method is a non-contact optical technique to measure the contour deformation, strain and stress values. In order to obtain the stress and strain values, three methods have been used to investigate the tensile properties, which are experimental, strain gauge measurement, and DIC methods.

Estimation of Digital Image Correlation (DIC) Performances
2007Optical full-field measurement techniques are promising tools for experimental analyses of materials and structures. While they are widely used, they still suffer from the lack of a complete metrological characterisation. The collaborative work carried out by the workgroup “Metrology” of CNRS research network 2519 aims at contributing to a systematic ...

Active Slip System Identification in Polycrystalline Metals by Digital Image Correlation (DIC)
Experimental Mechanics, 2016In this paper, a novel approach was proposed to increase the confidence of active slip system identification in polycrystalline metals. The approach takes advantage of microscale deformation tracking via Digital Image Correlation (DIC) combined with scanning electron microscopy (SEM).
