Global DIC

The purpose of this document is to provide good-practice 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 or other formal training and hardware and software-specific documentation) as well as a reference for experienced users, to refresh their fundamentals knowledge and skill sets and assist them in troubleshooting DIC measurements. The Good Practices Guide (GPG) focuses on good practices for DIC measurement setup, image correlation, and basic post-processing of DIC data for strain computations. The scope of the current edition of the GPG is limited to common laboratory test conditions (which are outlined in the GPG). Our intention is to incorporate good practices for complex test conditions, and their associated additional challenges, in a future edition of the GPG.
