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 — one of our long­stan­ding cus­to­mers — pro­vi­des on the fol­lo­wing web­site their rese­arch pro­ject. They ana­ly­ze the accu­ra­cy of digi­tal image cor­re­la­ti­on within the scope of rein­forced con­cre­te. Prof. Dr. Wal­ter Kauf­mann and Dr. Jai­me Mata Fal­cón are mem­bers of the project.
