Digital Image Correlation (DIC) is a 3D full-field, non-contact optical technique to measure contour, deformation, vibration and strain on almost any material. The technique can be used with many tests including tensile, torsion, bending and combined loading for both static and dynamic applications.
The DIC method can be applied from very small (micro) to large testing areas – and the results are readily comparable with FEA results or strain gauges.
The video below shows a Ball Inflation Test with an 8 Multicamera Digital Image Correlation System, the test was developed in partnership with the University Ljubljana – Faculty of Mechanical Engineering.
In this second video below we show a Double-sided Tensile Test with a 4 Multicamera Digital Image Correlation System.
