The purpose of the DIC Challenge is to advance the practice of DIC through collective efforts that point to optimum methodologies. The DIC Challenge is conducted under the auspices of the Society for Experimental Mechanics (SEM) and iDICs under the direction of the DIC Challenge board (see below).
Scope and Datasets
The DIC Challenge consists of several specific challenges:
- 2D-DIC Challenge
- Stereo DIC Challenge
- Huge Strain Challenge
- Digital Volume Correlation (DVC) Round Robin (links coming soon)
- Scanning Electron Microscope DIC (SEM-DIC) Round Robin
The goal of the 2D-DIC and Stereo-DIC Challenges is to provide a framework within which all codes can be tested, validated, and improved for their intended use. Both commercial codes and university codes are included. The use of a common image data set (with both experimental and synthetic images) removes the experimental errors associated with multiple hardware setups created by a typical, specimen-based, round-robin style test. The DIC code itself is then isolated and more easily evaluated independent of other experimental considerations.
The goal of the Digital Volume Correlation (DVC) Round Robin and Scanning Electron Microscope DIC (SEM-DIC) Round Robin is collectively building greater knowledge about these specialized image techniques for DIC, and investigating the optimum image parameters for each image modality.
When a specific challenge has been completed, all information is freely disseminated and open to all. The open availability allows researchers to download the images and compare with the published results from the participating codes.
