Technology Overview
VIC-2D uses our optimised correlation algorithms to provide full-field displacement and strain data for mechanical testing on planar specimens. Actual, in-plane movement can be determined for every point within the measurement area, as well as the many strain tensors.
VIC-2D can measure in-plane displacements and strains from 50 microstrains to 2000% strain and above, for specimen sizes ranging from 10m. Setup is simple, and specimen preparation only requires the application of a random speckle pattern.
Measurement Systems
We offer complete turn-key measurement systems for a wide range of full-field in-plane deformation measurement tasks. Our systems and analysis software are designed with the user in mind and are simple to set up and operate. Some of the features of our systems include:
- White-light system does not require lasers
- No calibration required
- Simple specimen preparation using paint
- Real-time data processing (>50Hz)
- Syncronised load data acquisition
- Available analog output for machine control
- Very high strain and displacement limits
- Sample size 10m possible
We also provide components as well as custom measurement systems for demanding applications including high temperature, higher speeds, and very small- or large-scale samples. Please contact us at DIC@eptworld.com if you would like to discuss your applications.
Application
The Vic-2D system is used where strain distributions need to be measured on flat specimens. Applications include fracture mechanics (COD measurement), bi-axial tension tests of films, determination of strain localization around cracks or notches as well as many applications in FE model verification.
