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. In other words, you can see an FEA-style picture to visualize strain and displacement
over the full two-dimensional surface of the test specimen. This powerful capability unlocks the true story of the material
behavior and allows materials testing professionals to analyze a number of advanced strain characteristics after the test.
The technique of DIC has been around for more than a decade. However until now, many users have struggled with a complex
user interface and synchronization problems. In response, the Instron® DIC Replay package is streamlined for the materials
testing community with an interface that is refreshingly simple and familiar. Additionally, Instron’s DIC package features built-in
synchronization of DIC images with test data collected, including load, position, and more. It is a DIC package that a capable
materials testing professional can use easily.

Features

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

* 2D analysis is appropriate where surface height deformation
t is negligible

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.
Method Saving
Save strain/displacement and plot methods to recall and
apply to other specimens.
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.
