The VIC-2D™ System

Technology Overview

Vic-2D uses our optimized 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 Lagrangian strain tensor.

Vic-2D can measure in-plane displacements and strains from 50 microstrain to 2000% strain and above, for specimen sizes ranging from <1mm to >10m. Setup is simple, and specimen preparation only requires the application of a random speckly pattern. No special illumination or lasers are required.

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)
  • Synchronized load data acquisition
  • Available analog output for machine control
  • Very high strain and displacement limits
  • Sample size <1mm and >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 Engineering@correlatedsolutions.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.
