Civil & structural testing incorporates the measurement of displacements & strains under loading of; bridges, buildings, tunnels, dams, and roads.,
Digital Image Correlation (DIC) and Point (Marker) Tracking is often performed for civil & structural testing for the following applications, including;
- Strain concentration (& crack growth) measurements of additive (printed) concrete
- Displacement (deflection) measurements of bridges under loading
