DIC Replay 2D Digital Image Correlation Software - 1

DIC REPLAY 2D Digital Image Correlation Software Digital Image Correlation (DIC) is an optical technique that compares images of a tested specimen’s surface to generate full-field strain and displacement maps. This powerful tool enables materials testing professionals to analyze advanced strain characteristics by visualizing strain and displacement over the full two-dimensional surface of the specimen. Though the technique of DIC has been around for more than a decade, many users have struggled with complex interfaces and problems with synchronization. Instron’s DIC Replay package is streamlined for the materials testing industry with a simple and familiar interface along with built-in synchronization of DIC images with collected test data, including load, position, and more. Full Field Strain and Displacement Method Saving Visualize strain and displacement over the full surface of a two dimensional object*. Displays include axial strain (εyy), axial displacement (dy), transverse strain (εxx), transverse displacement (dx), shear strain, maximum normal strain, and minimum normal strain. Save strain/displacement and plot methods to recall and apply to other specimens. Simple Display Options Adjust display options using intuitive graphical icons. Options include: • A variety of color palettes for contour maps • Automatic or fixed scaling options • Display gridlines to show data point locations • A toggle to show or hide the raw sample images Virtual Gauges Snap on and resize strain gauges or extensometers to analyze strain behavior over a specific area of the test specimen or the average strain between two points. Integration with Materials Testing Software View and plot results against the test data collected with Bluehill 3 Software — no additional synchronization hardware or cabling required. Flexible User License Users can install the DIC Replay software on many PCs while ensuring secure access through a portable USB dongle. This dongle acts like a key to open the software and allows users to process data away from the testing machine (e.g. on an office laptop) or without a network connection. * 2D analysis is appropriate where surface height deformation is

DIC Replay 2D Digital Image Correlation Software - 2

DIC REPLAY | 2D Digital Image Correlation Software SOFTWARE OVERVIEW Instron® DIC Replay Software is a self-contained 2D DIC package. The software consumes images and calibration data saved by Instron’s Advanced Video Extensometer (AVE) and works in a post-processing mode. The user interface leverages the same tabbed style and graphical design of Bluehill® Software. In fact, there are only three screens to sort, analyze, and plot DIC results. Sort Data with a Logical Project Tree • Browse and play raw image sequences from tested specimens • Explore calculated full-field displacement and...

DIC REPLAY | 2D Digital Image Correlation Software APPLICATIONS 2D full-field strain and displacement maps are useful for a number of diverse applications, including: visualizing material behavior on coupons or components, checking specimen alignment, and ensuring that localized strain occurs within the gauge length of a conventional extensometer. Check specimen preparation techniques by comparing one specimen to the next and looking for localized strain concentrations. Check for standards compliance by identifying localized strain that falls outside of the standard gauge length or clip-on...
