Multiscale displacement field measurements of compressed mineral-wool samples by digital image correlation.

We propose a multiscale approach to determine the displacement field by digital image correlation. The displacement field is first estimated on a coarse resolution image and progressively finer details are introduced in the analysis as the displacement is more and more securely and accurately determined. Such a scheme has been developed to increase the robustness, accuracy, and reliability of t...

Displacement monitoring of a Long-Span Arch Railway Bridge using Digital Image Correlation (DIC)

There is an escalating demand for condition monitoring enhancement of transport infrastructures worldwide. Bridges are of vital importance in transportation infrastructure and need such monitoring. In this research, a non-contact vision-based technique called Digital Image Correlation (DIC) was used to calculate the bridge displacements. A high frame rate camera with 4K capability was used for ...

Displacement/strain measurements using an optical microscope and digital image correlation

Dwayne D. Arola University of Maryland Baltimore County Department of Mechanical Engineering Baltimore, Maryland 21250 Abstract. We conduct displacement/strain measurements on the microscale using light microscopy and digital image correlation DIC . Errors in the measurements attributed to the optical arrangement and aberration induced at high magnification are identified using a warping functi...

applying digital image correlation method to measure flow field

in this study digital image correlation (dic) technique combined with a high speed video system was used to predict movement of particles in a water model. comparing with particle-image velocimetry (piv) technique, it provides a low cost alternative approach to visualize flow fields and was successfully employed to predict the movement of particles in a water model at different submergence dept...
