NIST (National Institute of Standards and Technology) using Vic-3D for digital image correlation (DIC)

NIST is using the Vic-3D digital image correlation (DIC) system to analyze stress in bridges. By using DIC, they try to understand the impact of stresses and strains on the metal connectors of bridges in order to avoid damage or failure.

NIST is pre-straining a wide plate with digital image correlation (DIC) to determine the small-scale specimen sectioning plan:

NIST is conducting a CWP test with digital image correlation (DIC) to determine local and remote strains used to determine the Tensile Strain Capacity of a flawed pipe girth-weld:

NIST is making an SE(T) test with digital image correlation (DIC) showing the asymmetric strain gradient of a specimen notched in the heat-affected zone:

DIC measurements on structural concrete

The ETH Zürich – on of our longstanding customers – provides on the following website their research project. They analyse the accuracy of digital image correlation within the scope of reinforced concrete. To the project members belong Prof. Dr. Walter Kaufmann and Dr. Jaime Mata Falcón.
