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.
