Guidelines for conducting DIC measurements in conjunction with mechanical testing of a planar test piece
This guide is designed to be both a primer training document geared towards new practitioners of DIC (supplementing vendor-based documentation) as well as a reference for experienced users. The Good Practices Guide (GPG) focuses on measurement setup, image correlation, and basic post-processing of DIC data for strain computations.
The purpose of the DIC challenge is to supply the image correlation community with a set of images for software testing and verification. This includes both commercial codes and university codes. All the information is freely disseminated at the DIC Challenge website and participation in the challenge is open to all.
Test images have been created both experimentally and synthetically. The DIC Challenge committee members will evaluate the results from each code and report them in a journal paper. Details of the creation of the images will also be recorded in a published paper so participants can understand how the images were created.
Digital image correlation is a non-contact means of measuring motion and deformation using digital images of the object of interest. It’s used for a wide variety of applications from characterizing material properties to identifying structural damage and quality testing in manufacturing.
