DIC Challenge

Purpose

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).

Meetings

We meet twice each year: in June at the Society for Experimental Mechanics Conference, and in November at the International DIC Society Conference. These meetings are open to the community and recently have been hosted in a hybrid online and in-person format.

Current Challenges

Currently, the DIC Challenge consists of the following specific challenges.

The goal of the 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.
