Simply see more: the 2D DIC software option for ZwickRoell videoXtens systems

The 2D DIC option does not require additional hardware. The software option is simply combined with the videoXtens and expands the functionality of the already installed strain measurement system

It allows for live strain measurement with a single extensometer, after which the 2D DIC analysis can be carried out.

ZwickRoell array systems offer you high resolution combined with a large field of view. They include several cameras, such as the videoXtens 2-120 HP, which allow you to simply see more in 2D DIC mode.

The ZwickRoell 2D DIC option makes local strains visible in 2D over the entire specimen surface. In combination with the standard strain measurement, you gain valuable additional information on specimen behavior for specimens that maintain a plane surface throughout the test. You are further supported by numerous analysis tools and an immediate display of the results in the form of various diagrams.

A number of examples can be found on the Digital Image Correlation page.

Convenient evaluation with testXpert III

The 2D DIC option was developed in-house at ZwickRoell and is fully integrated in testXpert III. With just one software system, live measurement and 2D DIC-analysis are performed and all measured values are managed.

  • Measured values, test results and images are stored, managed and evaluated together. You can easily and extensively analyze all measured values with each other. Strain values of a gauge length defined in the 2D DIC can be displayed and evaluated in a stress-strain curve.
  • You will reach your goal quickly and with just a few clicks: by specifying a workflow, you are guided step by step from setup to analysis and display of the measured values.
  • Prepare analysis parameters once, then save them in testXpert and use them over and over.
  • Reliable results: the 2D DIC-measured values are synchronized with the measured values of the testing machine.
  • Through the test re-run option for each evaluation a new specimen is added whenever you choose. This makes evaluation retrievable.

DIC setup: go with the (work) flow

Operating the 2D DIC is simple and intuitive. By specifying a workflow, you are guided step by step from setup to analysis and display of the measured values.

Analysis tools

Analysis tools in 2D DIC

  • Measuring points: these can be placed in any desired locations within a strain map.
  • Gauge lengths or virtual extensometers: establish two points on the strain map, between which the change in distance is to be determined.
  • Intersections: the strain progression is visualized along the lines. The intersection deforms with the specimen. In addition, there is an intersection stack through which selected time steps are displayed in a diagram, making the time-based development of the intersection visible.
  • Virtual strain gauges: for the virtual strain gauges, you can individually define the position, size and angle. In addition, multiple virtual strain gauges can be placed on top of each other at different angles. For example, two virtual strain gauges can be combined to form a biaxial strain gauge with measuring grids oriented at 90° to each other. The virtual strain gauges can save you a lot of time and cost.

Creation of graphs / diagrams

Graphical display / diagram

The following measured values can be displayed as strain maps and in diagrams:

  • Displacements in X direction
  • Displacements in Y direction
  • Local longitudinal strains Ɛx
  • Local transverse strains Ɛy
  • Local shear strains Ɛxy
  • Maximum normal strains
  • Minimum normal strains
  • Poisson's ratio
  • Equivalent Von Mises strains

Vector maps can be displayed in all strain maps, showing the main strain directions.

Export options
