Application of Digital Image Correlation technique to Erichsen Cupping Test

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...

Fracture Parameter Evaluation Using Digital Image Correlation Technique

Fracture and failure characterization of materials have been a crucial issue regarding reliable structural design. Stress Intensity Factor (SIF) is one of the most commonly used material parameters for more purpose. This study utilized Compact Tension (CT) Specimen test to determine mode-I SIF of polycarbonate material. Force, displacement and images of the near crack tip region were simultaneo...

Application of Multiple Digital Image Correlation Sensors in Earthquake Engineering

As structural testing has become more expensive, researchers are pushing to capture more and better data with each structural test conducted. Digital image correlation (DIC) is a tool that is gaining popularity as one way to capture more detailed information in testing programs. In threedimensional DIC (3D-DIC), the measured object is photographed with a pair of digital cameras before and after...

Digital Image Correlation

Applying Digital Image Correlation to Biological Materials

Digital image correlation has become a common method for determining mechanical properties of rigid engineering materials. By comparing digital images of the material before and after deformation, strain and displacement response can be determined. In the current work, we expand this method for use on soft biological materials, in particular skin. Specifically, we show that digital image correl...
