Digital Image Correlation (DIC) is an optical method that compares images of a tested specimen’s surface to yield complete field strain and displacement maps. It develops pictures that can be utilized to visualize strain and displacement across the full two dimensional (2D) surface of the test specimen.
The DIC Replay Software is a self-contained 2D DIC package. The software consumes images and calibration data saved by the Instron® Advanced Video Extensometer (AVE) and operates in a post-processing mode. The user interface leverages the same graphical design and tabbed style of Bluehill®.
Standard Features
- Virtual strain gauges
- Virtual extensometers
- Full field strain and displacement maps for axial strain (Eyy), transverse strain (Exx), axial displacement (Ey), shear strain (Exy), transverse displacement (Ex), maximum normal strain, and minimum normal strain
- Plot generation
- Method saving
- User defined image collection rate up to 50 Hz
- Synchronization with Bluehill test data (position, load, etc.)
- Three modes of operation (real time strain through AVE, post-processing DIC, or both)
Benefits
- Examine strain and displacement on the flat surface of a part or component where traditional extensometers are unfeasible
- View materials testing phenomenon, such as localized necking, discontinuous yielding, and more
- Visualize and detect cracks that are not noticeable with naked eye
- Visualize the side profile of a flat flexure or compression specimen to discern strain behavior
- Check for standards compliance by identifying localized strain that falls beyond the standard gauge length
- Check specimen preparation methods by comparing one specimen to the next
