Traditionally, strain gauge, extensometer, and reflection tracking markers have been used to measure the deformation of materials under loading. However, anisotropy inhomogeneity most biological restricted accessibility real field. Compared video digital image correlation has advantage providing full-field displacement as well information. In this study, a method (DIC) measurement system was em...

Optical coherence elastography (OCE) based on digital volume correlation (DVC) has the advantages of full 3D displacements and strain tensor quantification. However, measurement results are often unreliable due to poor quality optical tomography (OCT) speckle patterns. This paper proposes an image evaluation index OCT-DVC (CMGG, combined mean attenuation intensity, breadth dispersion gray level...

Abstract The primary aim of the present study is to explore use, advantages and potential two advanced data acquisition techniques – 3D scanning digital image correlation (DIC), in testing metallic structures. a novel method for capturing full outer geometry an object. It being increasingly used experimental studies determination dimensional parameters characterisation local global imperfection...
